Is it possible to have a regular polygon whose interior angle is 45 degree?

Answer. No it is not possible to have a regular polygon each of whose interior angle is 45°.

Is it possible for a regular polygon to have an interior angle measure of 130 explain?

The sum of the exterior angles is always 360° and we can use this fact to find the number of sides. The number of sides has to be a natural number, so 7.2 is not possible, therefore 130° is not possible for the angles of a regular polygon.

Is it possible for a regular polygon to have an interior angle of 72?

A regular polygon has equal exterior angles of 72°. (a) Calculate the size of each interior angle in the regular polygon. We do this by subtracting the exterior angle of 72° from 180°. The answer is 180° – 72° = 108°….Question 2.

(a) a regular decagon exterior = °
(b) a regular pentagon exterior = °
interior = °

Why can’t 173 degrees have interior angles?

If you enter 173 degrees, you don’t get an integer for the number of sides because there is no such polygon.

How many sides does a regular polygon have if each interior angle has a measure of 172 degrees?

Each exterior angle = 180 – 172 = 8 degrees. = 45 sides.
