its a heptagon
The formula for the sum of the measures of the interior angles of a regular polygon is (n-2)180. Set this equal to 900 and solve for n to find the number of sides in the polygon. 900 = 180(n-2) 900 = 180n - 360 180n = 1260 n = 1260/180 n = 7
Only when it is a regular polygon that all interior angles are of equal measure

A formula for this question is that the total measure of the interior angles of a polygon is 180 degrees multiplied by 2 less than the number of sides. For a seven sided polygon, this formula yields 180 X 5 = 900 degrees.
Only if the polygon is "regular".
it's a heptagon
It has (900+360)/180 = 7 sides

A regular polygon having an interior angle measure of 168o has 30 sides and is called a triacontagon.
A formula for this question is that the total measure of the interior angles of a polygon is 180 degrees multiplied by 2 less than the number of sides. For a seven sided polygon, this formula yields 180 X 5 = 900 degrees.
a convex polygon has 6 sides . What is the sum of the measure of its interior angles?
Only if the polygon is "regular".
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.
