The new lesson focuses on formulating the relationships of interior and euterior uelen of convex polygons. Before you proceed to the new leason, answer Activity 1 and 2. Ready? Activity 1: Materials needed: Pencil, paper, protractor Sum of the Interior Angles of a Conves Polygon Procodures: 1. Draw a triangle. Using a protractor, detemine the measure of its interior atigles and determine the sum of the interior angles. 2 Draw a quadrilateral. Then fix a vertex and draw diagonals from this vertex. Then answer the following 2 How many diagonals are drawn from the fixed vertex? b. How many triangles are formed by this/these diagonal(s)? C. Without actually measuring can you deternmine the sum of the interior angles of a quadrilateral?.
