  1. Chapter 11.1 Angle Measures in Polygons

  2. Sum of the Measures of the Interior Angles of a Convex Polygon… (n-2) * 180

  3. Chapter 11.2 Areas of Regular Polygons

  4. The Measure of the Central Angle of a Regular Polygon: 1/n * 360 (n = the number of sides)

  5. Area Find the area of the regular pentagon. Step 1: Find the central angle. Step 2: Redraw the Triangle you are working with Step 3: Find the Apothem (use trig!) Step 4: Find the Perimeter (use trig!) Step 5: Use the Area formula for Regular Polygons

  6. Table Activity… then… HOMEWORK Pg. 665: 6-19, 22-25, 29-36 Pg. 672: 9-24
