Geometry Chapter 1: Essentials of Geometry Section 1.6 – Classify Polygons SWBAT: classify polygons. Common Core: G-­‐CO Experiment with transformations in the plane 
G.CO.1. Know precise definitions of angle, circle, perpendicular line, parallel line, and line segment, based on the undefined notions of point, line, distance along a line, and distance around a circular arc. Vocabulary: polygon-­‐ side and vertex; convex, concave, n-­‐gon, equilateral, equiangular, regular Geometry Chapter 1: Essentials of Geometry Example 1: Identify Polygons The term __________________________, where n is the number of a polygon’s sides, can also be used to name a polygon. For example, a polygon with 14 sides is a 14-­‐gon. In an ___________________________ polygon, all sides are congruent. In an ________________________________ polygon, all interior angles are congruent. A _______________________ is a convex polygon that is both equilateral and equiangular. Geometry Chapter 1: Essentials of Geometry Example 2: Classify polygons Example 3: Find side lengths a. A table is shaped like a regular hexagon. The expression shown represents side lengths of the hexagonal table. Find the length of a side. b. The expression 8𝑦° 𝑎𝑛𝑑 (9𝑦 − 15)° represent the measure of two of the angles in the table from example 3. Find the measure of an angle. Homework: pgs. 44 – 45 #’s 3 – 29 ODD and 40
