Introduction on Circle

1. A circle is defined as all points in a plane that are a fixed distance from a fixed center point. This fixed distance is called the radius.
2. Lines can intersect a circle in three ways: not at all, at one point (a tangent), or at two points (a secant). The longest secant that passes through the center is the diameter.
3. An arc is the portion of the circle cut off by a central angle. The measure of an arc is equal to the measure of its central angle.

The document defines key terms related to circles such as radius, circumference, chord, diameter, arc, and sector. It explains that a circle is a collection of points equidistant from a fixed center point and defines the radius as the segment from the center to the edge. The circumference is the distance around the entire circle. Two circles are congruent if their radii are the same measure and concentric if they share the same center. A chord connects two edge points, a diameter passes through the center, and an arc is part of the edge between two points. A sector is the region between two radii and their connecting arc.

Vertebrates

Vertebrates are animals that have backbones. They are further classified into mammals, fish, birds, amphibians, and reptiles. Mammals are warm-blooded and give birth to live young, while fish, amphibians and reptiles are cold-blooded and hatch from eggs. Birds are warm-blooded but hatch from eggs. Each group has distinguishing characteristics like scales, feathers, fins or fur that help them survive in different environments. The document provides examples of common vertebrates for each classification.

10 technology trends to watch in the COVID- 19 pandemic

The document discusses 10 technology trends that have emerged or accelerated due to the COVID-19 pandemic, including online shopping/robot deliveries, digital/contactless payments, remote work, distance learning, telehealth, online entertainment, supply chain 4.0, 3D printing, robotics/drones, and 5G/ICT. It notes that the pandemic has demonstrated the importance of digital readiness for businesses and societies to function during crises. However, ensuring inclusive access to technology will continue to be a challenge as digitization progresses.

Personality test by dalai lama

This personality test document instructs the reader to rank animals by preference, describe words in one word each, name a person associated with different colors, and provide a favorite number and day of the week. It then provides interpretations for each answer: the animals represent priorities like career and love, the word descriptions imply aspects of personality, the colors relate to important people, and the number and day predict when a wish will be received.

Buddhism

The document provides an overview of Buddhism, including its founder Siddhartha Gautama, also known as the Buddha, the history and spread of Buddhism, core beliefs and teachings such as the Four Noble Truths and Noble Eightfold Path, different types of Buddhism, key symbols, and festivals. It describes how Gautama was born a prince in Nepal and became enlightened under the Bodhi tree, establishing the foundations of Buddhism. His teachings on achieving inner peace through morality, meditation, and wisdom were spread after his death and Buddhism became the dominant religion in India under Emperor Ashoka.

Quadrilaterals

The unknown angle is 105 degrees.

Area

This document defines area and perimeter, and provides formulas to calculate the area of different shapes. It defines area as the space occupied by a flat shape and explains that area is measured in square units. Formulas are given for calculating the area of a square, rectangle, parallelogram, triangle, and trapezoid using measurements of sides and other key dimensions. The key difference between perimeter and area is also explained, with perimeter being the distance around a figure and area being the space inside measured in square units.

Angle

This document defines different types of angles and their measurements. It describes an angle as the figure formed by two rays sharing a common vertex point. The types of angles are acute, right, obtuse, straight, and reflex angles with measurements between 0 and 360 degrees. It also defines relationships between adjacent angles which are complementary if their sum is 90 degrees and supplementary if their sum is 180 degrees. Vertical angles are formed at the intersection of two lines and are always equal.

Solid Figure

This document defines and describes basic solid figures and their components. It explains that a solid figure is a 3D object with length, width, and height or thickness. The key parts are faces, edges where faces meet, and vertices where three or more faces connect. It provides examples of prisms and pyramids, which are named after the shape of their base, and mentions curved surface solids.

Divisivility Rules

The document discusses how Anna wants to share her 40 chocolates equally among her friends. It explains different ways to check if a number is divisible by 2, 3, 5, 9, or 10. Based on checking if 40 is divisible, it determines that Anna can divide the chocolates into 2, 5, or 10 equal groups.

Wound healing PPT

This document provides an overview of wound healing, its functions, stages, mechanisms, factors affecting it, and complications.
A wound is a break in the integrity of the skin or tissues, which may be associated with disruption of the structure and function.
Healing is the body’s response to injury in an attempt to restore normal structure and functions.
Healing can occur in two ways: Regeneration and Repair
There are 4 phases of wound healing: hemostasis, inflammation, proliferation, and remodeling. This document also describes the mechanism of wound healing. Factors that affect healing include infection, uncontrolled diabetes, poor nutrition, age, anemia, the presence of foreign bodies, etc.
Complications of wound healing like infection, hyperpigmentation of scar, contractures, and keloid formation.
