Pentagon/Internal angle
What is the value of one interior angle in a pentagon?
108 degrees
There are 5 interior angles in a pentagon. Divide the total possible angle by 5 to determine the value of one interior angle. Each interior angle of a pentagon is 108 degrees.
How do you find the interior angle of a pentagon?
Method 1
- The exterior angle is 360 ÷ 5 = 72 ∘ .
- The interior angle is 180 − 72 = 108 ∘ .
- The sum of interior angles is ( 5 − 2 ) × 180 = 540 ∘ .
- The interior angle is 540 ÷ 5 = 108 ∘ .
- The exterior angle is 180 − 108 = 72 ∘ .

What’s the angle of a pentagon?
| Pentagon | |
|---|---|
| An equilateral pentagon, i.e. a pentagon whose five sides all have the same length | |
| Edges and vertices | 5 |
| Internal angle (degrees) | 108° (if equiangular, including regular) |

How do you find the sum of 3 angles in a pentagon?
In a pentagon, there are 5 sides, or . Substitute and find the total possible angle in a pentagon. There are 5 interior angles in a pentagon. Divide the total possible angle by 5 to determine the value of one interior angle. Each interior angle of a pentagon is 108 degrees. The sum of three angles in a pentagon is:
How many degrees does a pentagon have 3 triangles?
Remember, the 3 angles of any triangle always add up to 180 degrees. So if you have three triangles making up your pentagon, then your angles will always add up to 540 degrees (3 * 180 degrees). No matter how you stretch your pentagon, you still have your three triangles.
What is the measure of the fifth angle of an irregular pentagon?
An irregular pentagon has four known angles of 135, 78, 119, and 117 degrees. What’s the measure of the fifth angle? To answer this question, you’ll use your knowledge that the sum of the interior angles of any pentagon is always 540 degrees.
