Question

Find the measure of an interior angle an exterior angle of a regular polygon with 5 sides .

Answer 1

to find the interior angle, it is (n-2)180
so it would be 5-2(180)
which is 3*180

Answer 2

360/5=72
(180-72) = 108 - internal
360-internal = external

Answer 3

that is the sum of internal angles.
to get one interior angle, divide the sum of interior angles by 5.

Answer 4

To find all exterior angles, it is alway 360 in a regular polygon.
to find 1 exterior angle, it would be 360/5

Answer 5

so: 1 interior angle= 540/5
1 exterior angle=360/5

hope this helped! :)
