13 Μαρ 2012 · Secants and tangents are lines that intersect the circle at one or more points. This document defines and classifies different types of polygons. It discusses simple vs complex polygons, concave vs convex polygons, and regular vs irregular polygons based on their geometric properties.
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.
Polygons. Definitions, notes, examples, and practice test (w/solutions) Including concave/convex, exterior/interior angle sums, diagonals, n-gon names, and more...
A polygon is named by the number of its sides or angles. A triangle is a polygon with three sides. The prefixtri- means three. Prefixes are also used to name other polygons. When you studied quadrilaterals in Lesson 8–1, you learned several terms that can be applied to all polygons. An equilateral polygon has all sides congruent, and an ...
10 Ιουλ 2020 · Polygons are named based on the number of sides and can be regular, meaning all sides and angles are congruent, or irregular. The interior angles of any polygon sum to (n-2)×180°, where n is the number of sides. The exterior angles of any polygon sum to 360°. For a regular polygon, each exterior angle measures 360°/n.
The document outlines a detailed 60-minute lesson plan on polygons for a 7th grade mathematics class. The objectives are for students to define polygons, illustrate different polygon classifications, and appreciate polygons' real-world applications.
The parts of a polygon. The straight lines of a polygon are called edges or sides. The corners are called vertices. Vertex is the Latin word for corner. vertex. edge or side. Polygons contain two main types of angles, interior angles and. exterior angles. Shown below is a regular pentagon.
