How many degrees is a 9 sided shape?

140 °Excellent! So the interior angle of a 9 -sided polygon is 140 ° .

How many degrees is a 8 sided shape?

1080 degreesAn octagon has eight sides, so the sum of the angles of the octagon is 180(8 – 2) = 180(6) = 1080 degrees. Because the octagon is regular, all of its sides and angles are congruent. Thus, the measure of each angle is equal to the sum of its angles divided by 8.

What is a shape with 10 sides called?

decagonIn geometry, a decagon (from the Greek δέκα déka and γωνία gonía, “ten angles”) is a ten-sided polygon or 10-gon. The total sum of the interior angles of a simple decagon is 1440°. A self-intersecting regular decagon is known as a decagram.
