An angle is formed by two rays sharing a common endpoint called the vertex. An angle can be measured in degrees and named using symbols to indicate the vertex point and/or side points. There are several types of angles including acute (less than 90 degrees), obtuse (between 90 and 180 degrees), right (90 degrees), straight (180 degrees), and reflex (greater than 180 degrees). Angles can also be classified based on their relationship to each other, such as complementary angles whose measures sum to 90 degrees, or supplementary angles that sum to 180 degrees.

How to Split Bills in the Odoo 17 POS ModuleCeline George
Bills have a main role in point of sale procedure. It will help to track sales, handling payments and giving receipts to customers. Bill splitting also has an important role in POS. For example, If some friends come together for dinner and if they want to divide the bill then it is possible by POS bill splitting. This slide will show how to split bills in odoo 17 POS.
We all have good and bad thoughts from time to time and situation to situation. We are bombarded daily with spiraling thoughts(both negative and positive) creating all-consuming feel , making us difficult to manage with associated suffering. Good thoughts are like our Mob Signal (Positive thought) amidst noise(negative thought) in the atmosphere. Negative thoughts like noise outweigh positive thoughts. These thoughts often create unwanted confusion, trouble, stress and frustration in our mind as well as chaos in our physical world. Negative thoughts are also known as “distorted thinking”.
The French Revolution, which began in 1789, was a period of radical social and political upheaval in France. It marked the decline of absolute monarchies, the rise of secular and democratic republics, and the eventual rise of Napoleon Bonaparte. This revolutionary period is crucial in understanding the transition from feudalism to modernity in Europe.

This is a presentation by Dada Robert in a Your Skill Boost masterclass organised by the Excellence Foundation for South Sudan (EFSS) on Saturday, the 25th and Sunday, the 26th of May 2024.
He discussed the concept of quality improvement, emphasizing its applicability to various aspects of life, including personal, project, and program improvements. He defined quality as doing the right thing at the right time in the right way to achieve the best possible results and discussed the concept of the "gap" between what we know and what we do, and how this gap represents the areas we need to improve. He explained the scientific approach to quality improvement, which involves systematic performance analysis, testing and learning, and implementing change ideas. He also highlighted the importance of client focus and a team approach to quality improvement.

The Roman Empire A Historical Colossus.pdfkaushalkr1407
The Roman Empire, a vast and enduring power, stands as one of history's most remarkable civilizations, leaving an indelible imprint on the world. It emerged from the Roman Republic, transitioning into an imperial powerhouse under the leadership of Augustus Caesar in 27 BCE. This transformation marked the beginning of an era defined by unprecedented territorial expansion, architectural marvels, and profound cultural influence.
The empire's roots lie in the city of Rome, founded, according to legend, by Romulus in 753 BCE. Over centuries, Rome evolved from a small settlement to a formidable republic, characterized by a complex political system with elected officials and checks on power. However, internal strife, class conflicts, and military ambitions paved the way for the end of the Republic. Julius Caesar’s dictatorship and subsequent assassination in 44 BCE created a power vacuum, leading to a civil war. Octavian, later Augustus, emerged victorious, heralding the Roman Empire’s birth.
Under Augustus, the empire experienced the Pax Romana, a 200-year period of relative peace and stability. Augustus reformed the military, established efficient administrative systems, and initiated grand construction projects. The empire's borders expanded, encompassing territories from Britain to Egypt and from Spain to the Euphrates. Roman legions, renowned for their discipline and engineering prowess, secured and maintained these vast territories, building roads, fortifications, and cities that facilitated control and integration.
The Roman Empire’s society was hierarchical, with a rigid class system. At the top were the patricians, wealthy elites who held significant political power. Below them were the plebeians, free citizens with limited political influence, and the vast numbers of slaves who formed the backbone of the economy. The family unit was central, governed by the paterfamilias, the male head who held absolute authority.
Culturally, the Romans were eclectic, absorbing and adapting elements from the civilizations they encountered, particularly the Greeks. Roman art, literature, and philosophy reflected this synthesis, creating a rich cultural tapestry. Latin, the Roman language, became the lingua franca of the Western world, influencing numerous modern languages.
Roman architecture and engineering achievements were monumental. They perfected the arch, vault, and dome, constructing enduring structures like the Colosseum, Pantheon, and aqueducts. These engineering marvels not only showcased Roman ingenuity but also served practical purposes, from public entertainment to water supply.

2. ANGLE
• It is geometrical shape formed by joining two rays at their end-points. The two
components of an angle are “sides” and “vertex”. The side can be categorized
into terminal sides and initial sides (or vertical sides). An angle is usually
measured in degrees.
9. Parts of Angle
VERTEX – the common point where the
two rays meet.
ARMS – the rays that make up the angle.
DEGREES – the measure of the size of an
angle.
10. Naming Angles
One way is to use the ∠ symbol followed by three letters.
• The first and third letters indicate points on the two arms.
• The letter in the middle is the vertex.

C

∠ ABC ∠ CBA
11. Naming Angles
• Using the ∠ symbol only with the vertex point.
The angle would be called ∠B.
• By using the ∠ symbol followed by the letter or number between the angle.
This would be ∠1. A

13. Six Types of Angles
In Math, there are mainly 5 types of angles based on their direction. These
five angle types are the most common ones used in geometry. These are:
• Acute Angles
• Obtuse Angles
• Right Angles
• Straight Angles
• Reflex Angles
• Full Rotation
14. ACUTE ANGLE
An acute angle lies between 0 degree and 90 degrees, or in other words; an acute
angle is one that is less than 90 degrees.
15. OBTUSE ANGLE
An obtuse angle is the opposite of an acute angle. It is the angle which lies
between 90 degrees and 180 degrees or in other words; an obtuse angle is greater
than 90 degrees and less than 180 degrees.
16. RIGHT ANGLE
A right angle is always equal to 90 degrees. Any angle less than 90 degrees is an
acute angle whereas any angle greater than 90 degrees is an obtuse angle.
18. REFLEX ANGLE
Any angle that has a measure which is greater than 180 degrees but less than 360
degrees (which coincides with 0 degrees) is a reflex angle.
19. Full Rotation
An angle equal to 360 degrees is called full rotation or full angle. It is formed
when one of the arms takes a complete rotation to form an angle.
22. Pair of Angles
When two angles are paired, then there exist different angles, such as
•Complementary angles
•Supplementary angles
•Linear Pair
•Adjacent angles
•Vertically Opposite angles
23. Complementary and Supplementary
Angles
If the sum of two angles is equal to 180°, then they are SUPPLEMENTARY
ANGLES.
If the sum is equal to 90°, then they are called COMPLEMENTARY ANGLES.
24. Linear Pair
When the non-common arms of adjacent angles are just opposite to each other,
or they extend in the opposite direction, then they are called linear pairs. By
linear they form a straight line.
25. Adjacent Angles
When two angles are connected with one common arm and have one common
vertex and also the non-common arms are either side of the common arm, then
they are called adjacent angles.
26. Vertical Angles
When two lines intersect each other at a single point (called vertex), then the
angle formed on either side of the common vertex is called vertical angles or
vertically opposite angles.
27. 1. The sides of ∠YVW
2. The sides of ∠XVY
3. The angle(s) adjacent to ∠ZVW
4. The angle(s) adjacent to ∠XVZ
5. The angle(s) adjacent to ∠YVZ
6. The side common to ∠XVY and ∠YVZ
7. The side common to ∠XVZ and
∠ZVW
8. The side common to ∠XVZ and ∠ZVY
9. The side common to ∠XVY and
∠YVW
10.The common vertex.
