Divide the number of sides into 360 degrees and then subtract your answer from 180 degrees to give you the interior angle.
For example a regular hexagon has 6 equal sides and 360 divided by 6 = 60 degrees (the exterior angle)
180 - 60 = 120 degrees (the interior angle)

What is the measure of an interior angle that has a regular polygon with 20 sides?
Each interior angle will measure 162 degrees
How do you measure sides of a regular polygon if each interior angle is 120?
A regular polygon with each interior angle measuring 120 degrees is a hexagon.
What is the interior angle of a twenty-four-sided polygon?
If the polygon is regular, the measure of one interior angle of a 24 side polygon is 165 degrees.
If the measure of one interior angle of a regular polygon is 90 degrees how many sides does the polygon have?
The only regular polygon with an interior angle of 90 degrees is the square, which has four sides. Other polygons can have an interior angle of 90 degrees, but they would not be regular polygons.
How can you get the measure of an interior angle if you have the measure of the exterior angle of a regular polygon?
It is: 180-exterior angle = interior angle because there are 180 degrees on a straight line
A regular polygon has an interior angle measure of 168 What kind of polygon is it?
A regular polygon having an interior angle measure of 168o has 30 sides and is called a triacontagon.
What is the measure of each interior angle of a fifteen sided regular polygon?
The measure of each interior angle of a fifteen sided regular polygon, a pendedecagon, is 156o.
If the measure of an interior angle of a regular polygon is 140 how many sides does the polygon have?
If the measure of an interior angle of a regular polygon is 140o, the polygon is a nonagon (sometimes called an ennagon) having 9 sides.
What is the measure of each interior angle of a 18 sided regular polygon?
The interior angle of an octdecagon, an 18 sided regular polygon, is 160o.
What is the measure of one interior angle of a regular polygon with 4 sides?
A regular polygon with 4 sides is a square. The measure of any interior angle of a square is 90 degrees.
What is the measure of an interior angle that has a regular polygon with 20 sides?
Each interior angle will measure 162 degrees
How do you measure sides of a regular polygon if each interior angle is 120?

What is the interior angle of a twenty-four-sided polygon?
If the polygon is regular, the measure of one interior angle of a 24 side polygon is 165 degrees.
What is the interior angle of a 18 sided polygon?
Providing that it is a regular polygon then each interior angle will measure 160 degrees
The measure of each interior angle in a polygon is 120 What is the name of the polygon?
A regular hexagon.
If the measure of one interior angle of a regular polygon is 108 how many sides does the regular polygon have?
A pentagon (five sided regular polygon) has interior angles of 108°.
How many sides does a regular polygon have if the measure of each interior angle is equal to 172 degress?
How many sides does a regular polygon have if the measure of each interior angle is equal to 172 degress ?
