And there are five angles. All sides are the same length congruent and all interior angles are the same size congruent.

One interior angle sum of exterior angles.

Interior angles of a pentagon. These are not the reflex angle greater than. An equiangular pentagon is a regular pentagon that has five equal sides and five equal angles. So the sum of the interior angles of a pentagon is 540 degrees.

Every regular polygon has exterior angles. Make sure each triangle here adds up to 180 and check that the pentagon s interior angles add up to 540 the interior angles of a pentagon add up to 540. Pentagons are two dimensional shapes characterized by five co planar sides that are connected to form enclosed figures.

To find the measure of the interior angles we know that the sum of all the angles is 540 degrees from above. Each of the five interior angles of a regular pentagon measures 108 degrees. Its interior angles add up to 3 180 540.

Now that you know that the sum of the interior angles of a pentagon is always 540 degrees you can use this information to help you solve problems involving pentagons. And when it is regular all angles the same then each angle is 540 5 108. For example you might be asked a question such as this one.

Created by rotating from the exterior of one side to the next. For instance in an equilateral triangle the exterior angle is not 360 60 300 as if we were rotating. An interior angle of a pentagon is equal to 108 degrees.

The sum of the interior angles of a pentagon is 540 degrees. That is a common misunderstanding. An irregular pentagon has four known angles of 135 78 119 and 117 degrees.

The properties of regular pentagons.
