Answer:
7. Regular polygon
8. 135
Step-by-step explanation:
7. A polygon having equal sides and equal angles is a regular polygon. A regular polygon has three parts: Sides. Vertices.
8. Because the octagon is regular, all of its sides and angles are congruent. Thus, the measure of each angle is equal to the sum of its angles divided by 8. Therefore, each angle in the polygon has a measure of 1080/8 = 135 degrees.
