Question

Given a regular octagon, find the measures of the angles formed by (a) two consecutive radii and (b) a radius and a side of the polygon.

Answer 1

A

Answer 2

can you explain how it is a

Answer 3

in any regular polygon angle formed by 2 consecutive radii equals to
=\[\frac{ 360 }{ n }*degree\]

Answer 4

n = no of sides in polygon

Answer 5

for octagon =360/8=45 degree

Answer 6

as one angle is 45 degree
so sum of other two angle =180-45=135

Answer 7

as two sides are equal so the will made equal angle to third side.....or angle made by them will be equal..by properties of isosceles triangles

Answer 8

so angle made =135/2=67.5 degree

Answer 9

we divide by 2 bcause both angle will be equal

Answer 10

x+x=135
2x=135
x=135/2=67.5degree
