Answer:
The measure of one angle in the regular octagon is:
135°
Step-by-step explanation:
Regular polygon--
A polygon is said to be regular if it is equilateral (i.e. all sides of the polygon are equal) and equiangular (i.e. all the internal angles of the polygon are equal).
Regular octagon--
It is a regular polygon consisting of 8 sides.
Each of the internal angles of the regular octagon is: 135 degrees.
( since the sum of all the internal angles of a regular polygon is: 1080 degrees.
and all the angles are equal.
so measure of one angle is: 1080/8= 135 degrees )
