Question

Find the measure of each angle of a regular octagon​

Answer 1

Sum of all angles of any octagon = 1080°

Measure of each side = $\frac{1080}{8}$  

                                   = 135°

Measure of each angle of a regular octagon is 135°.

Answer 2

Answer:

a regular octagon has equal sides and equal angles.

so the central angles created due the intersection of lines of opposite vertices

is = 360°÷8=45°

so, the vertical angle of an octagon = (180°-45°)= 135°
