What is the formula for interior angles?
The formula for calculating the sum of interior angles is ( n − 2 ) × 180 ∘ where is the number of sides. All the interior angles in a regular polygon are equal. The formula for calculating the size of an interior angle is: interior angle of a polygon = sum of interior angles ÷ number of sides.
How many sides does a polygon have with an interior angle of 108?
Answer. Each interior angle of the polygon is 108 degrees, so each exterior angle of the polygon is 180-108 = 72 degrees. So the number of sides is 360/72 = 5.
How many sides does a polygon have with an interior angle of 175?
72 sides
How many sides does a polygon have with an interior angle of 170?
36 sides
How many sides does a polygon have with an interior angle of 172?
45 sides
Can a regular polygon have interior angles that measure 72?
–> 5n = 360 –> n = 72. This is an integer, so a regular polygon with 72 sides would have interior angles measuring 175 degrees.
What is the interior angle of a 72 sided shape?
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.

Is there a 9 sided shape?
A nonagon is also called enneagon, which is derived from a Greek word called enneagonon, which means nine corners. The first use of the word nonagon dates back to the early 17th century, and has a Latin prefix (nona) and a Greek suffix (gon), making it a polygon with nine sides and nine angles.
