73, Angle Measure in Regular Polygons

1
7-3, Angle Measure in Regular Polygons

• Objectives
• Determine the measure of each angle in a regular
  polygon
• Find perimeters of similar polygons

2
Terms

• Radius the distance from the center of a circle
  to the circle
• Perimeter the distance around the outside of the
  shape

3
Formula measure of interior angles of a regular
polygonn number of side
4
Example find the size of the interior angles

• Using the formula n 6 (hexagon)
• Angle measure

5
Example Use the ratio of similarity to find the
perimeter of the larger polygon

• Given The perimeter of the smaller triangle is
  6 the ratio of similarity is 35
• (3)(x) (6)(5)
• 3x 30
• x 10
