PROPERTIES OF N-SIDED REGULAR POLYGONS. When students are first exposed to regular polygons in middle school, they learn their properties by looking at individual examples such as the equilateral triangles(n=3), squares(n=4), and hexagons(n=6).
Definitions, notes, examples, and practice test (w/solutions) Including concave/convex, exterior/interior angle sums, diagonals, n-gon names, and more...
Introduction. This document aims to guide the reader into the world of polytopes, focusing on the familiar setting of polygons, the two-dimensional polytopes. We will assume the reader is comfortable with the Cartesian plane and ordered pairs of numbers. Let's get right into it! Intuitively, polygons are certain 2-dimensional shapes.
In a regular polygon, all exterior angles are equal. The formula for the exterior angle of a regular polygon with n sides is:
Use the function you found in Exploration 1 to write a new function that gives the measure of one interior angle in a regular polygon with sides. Use the function in part (a) to fi nd the measure of one interior angle of a regular pentagon.
This booklet is about identifying and manipulating straight sided shapes using their unique properties Many clever people contributed to the development of modern geometry including: • Thales of Miletus (approx. 624-547 BC) • Pythagoras (approx. 569-475 BC)
Learn. Polygon Names. A polygon is a 2D shape with all its sides straight. Polygons are named primarily according to the number of sides. The names are listed below. It is worth knowing the names in bold red. For polygons with more than 12 sides, the. n-gon names are generally used: 13-gon, 14-gon, 15-gon, 16-gon and so on.
