What is the sum of the measures of the interior angles of a decagon

What is the sum of the measures of the interior angles of a decagon 10 sided polygon?

In 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°.

What is the sum of the measures of the interior angles of a dodecagon explain your answer?

To find the sum of the interior angles of a dodecagon, divide it up into triangles. and we get ten triangles. Because the sum of the angles of each triangle is 180 degrees , multiply 10 into 180 and we get 1800 degrees . So, the sum of the interior angles of a dodecagon is 1800 degrees .

How do you find the sum of the measures of the interior angles?

The formula for finding the sum of the measure of the interior angles is (n – 2) * 180. To find the measure of one interior angle , we take that formula and divide by the number of sides n: (n – 2) * 180 / n.

What is the measure of each exterior angle in a regular decagon?

Properties of regular decagons

Interior angle 144°
Exterior Angle 36°

What is the sum of the measures of the interior angles of a Heptagon?

A heptagon has 7 sides, so we take the hexagon’s sum of interior angles and add 180 to it getting us, 720+180=900 degrees .

How do you find the sum of the interior angles of a dodecagon?

The interior angles of a dodecagon are a bit harder. You can use this generic formula to find the sum of the interior angles for an n-sided polygon (regular or irregular): Sum of interior angles = (n-2) x 180° Sum of interior angles = 10 x 180° = 1800°
