The document defines and provides examples of different types of polygons. It explains that a polygon is a closed figure made of line segments that intersect only at their endpoints. Regular polygons have equal side lengths and interior angles, while irregular polygons do not have these properties. Various common polygons are defined, including triangles, quadrilaterals, pentagons, hexagons, and more. Examples of regular and irregular shapes are shown for each type of polygon.

Instructions for Submissions thorugh G- Classroom.pptxJheel Barad
This presentation provides a briefing on how to upload submissions and documents in Google Classroom. It was prepared as part of an orientation for new Sainik School in-service teacher trainees. As a training officer, my goal is to ensure that you are comfortable and proficient with this essential tool for managing assignments and fostering student engagement.
How to Create Map Views in the Odoo 17 ERPCeline George
The map views are useful for providing a geographical representation of data. They allow users to visualize and analyze the data in a more intuitive manner.
Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.

2024.06.01 Introducing a competency framework for languag learning materials ...Sandy Millin
http://sandymillin.wordpress.com/iateflwebinar2024
Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasn’t one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.
Synthetic Fiber Construction in lab .pptxPavel ( NSTU)
Synthetic fiber production is a fascinating and complex field that blends chemistry, engineering, and environmental science. By understanding these aspects, students can gain a comprehensive view of synthetic fiber production, its impact on society and the environment, and the potential for future innovations. Synthetic fibers play a crucial role in modern society, impacting various aspects of daily life, industry, and the environment. ynthetic fibers are integral to modern life, offering a range of benefits from cost-effectiveness and versatility to innovative applications and performance characteristics. While they pose environmental challenges, ongoing research and development aim to create more sustainable and eco-friendly alternatives. Understanding the importance of synthetic fibers helps in appreciating their role in the economy, industry, and daily life, while also emphasizing the need for sustainable practices and innovation.
2. A polygon is a closed figure made by joining
line segments, where each line segment
intersects exactly two others.
Polygon
3. Q: Is this a polygon? Why or why not?
A: No…
Polygons are closed figures.
4. Q: Is this a polygon? Why or why not?
A: No…
It is not made of line segments.
5. Q: Is this a polygon? Why or why not?
A: No…
Its sides do not intersect in
exactly two places each.
6. Regular Polygons
A regular polygon is a polygon whose sides are
all the same length, and whose angles are all
the same. The sum of the angles of a polygon
with n sides, where n is 3 or more, is
180° × (n - 2) degrees.
7. Are these regular polygons?
Why or why not?
A: No…
These sides are all the different lengths,
and the angles are all different.
8. Vertex
• The vertex of an angle is the point
where the two rays that form the
angle intersect.
9. Vertex of a Polygon
• The vertices of a polygon are the
points where its sides intersect.
21. Rhombus
A four-sided polygon having all four sides
of equal length. The sum of the angles of a
rhombus is 360 degrees.
22. Trapezoid
A four-sided polygon having exactly one pair of
parallel sides. The two sides that are parallel
are called the bases of the trapezoid. The sum
of the angles of a trapezoid is 360 degrees.
23. Pentagon
A five-sided polygon. The sum of the
angles of a pentagon is 540 degrees.
A regular pentagon: An irregular pentagon:
24. Hexagon
A six-sided polygon. The sum of the angles
of a hexagon is 720 degrees.
A regular hexagon: An irregular hexagon:
25. Heptagon
A seven-sided polygon. The sum of the
angles of a heptagon is 900 degrees.
A regular heptagon: An irregular heptagon:
26. Octagon
An eight-sided polygon. The sum of the
angles of an octagon is 1080 degrees.
A regular octagon: An irregular octagon:
27. Nonagon
A nine-sided polygon. The sum of the
angles of a nonagon is 1260 degrees.
A regular nonagon: An irregular nonagon:
28. Decagon
A ten-sided polygon. The sum of the angles
of a decagon is 1440 degrees.
A regular decagon: An irregular decagon:
29. Circle
A circle is the collection of points in a plane that are all
the same distance from a fixed point. The fixed point is
called the center. A line segment joining the center to
any point on the circle is called a radius.
30. Convex
A figure is convex if every line segment drawn between
any two points inside the figure lies entirely inside the
figure. A figure that is not convex is called a concave
figure.
Convex: Concave:
