Question

Work out the size of the interior angle of a regular octogon

Answer 1

Answer:

135°

Step-by-step explanation:

interior angle of regular polygon of n sides = (n-2)180°/n

Given n=8

interior angle of a regular octogon = 6*180/8

                                                           = 135°

HOPE IT IS HELPFUL

Answer 2

Answer:

If you want to know interior angle then

there is one formula.

sum of interior angle =(2n -4)*right angle (90degree)

In the place of n you have put the side regular octagon.

:interiors angle =(2n-4)*90 degree

=(2*8-4)*90 degree

=(16-4)*90 degree

=12*90 degree

=1080 degree

the interior angle of regular octagon is:1080 degree .

Glad I could help you.
