Unit 1 - Day 14
Why do you think these polygons are called regular polygons?
Why do the angles of the regular triangle (equilateral) have to equal 60°?
Why do the angles of the regular quadrilateral (square) have to equal 90°?
Why do the angles of the regular pentagon have to equal 108°?
Why do the angles of the regular hexagon have to equal 120°?
Determine the measure of each angle in a regular octagon (8 sided polygon). Explain how you found your answer.
Determine the measure of each angle in a regular decagon (10 sided polygon). Explain how you found your answer.
Use this formula to write an equation that will calculate the measure of each angle (A) of a regular polygon with n sides. Your equation should be of the form A = [expression involving n].
Use your equation to determine the measure of each angle of a regular 12-sided polygon.
Use your equation to determine the measure of each angle of a regular 20-sided polygon.
Each angle of a regular polygon measures 156°. Use your equation to determine the number of sides that the polygon has.
Each angle of a regular polygon measures 165°. Use your equation to determine the number of sides that the polygon has.
