  1. 10-3: Areas of Regular Polygons Warm-Up:

  2. The radius of a regular polygon is the distance from the center to a vertex. The apothem is the perpendicular distance from the center to a side. Find the measure of each numbered angle. a) b)

  3. Postulate 10-1: If two figures are congruent, then their areas are equal. Theorem 10-6: Area of a Regular Polygon 2) What is the area of a regular pentagon with an 8-cm apothem and 11.6-cm sides? If the side of a regular polygon is reduced to half its length, how does the perimeter of the polygon change? Explain.

  4. 3) The side of a regular hexagon is 16 feet. What is the are of the hexagon? Round your answer to the nearest square foot.
