In pentagon ABCDE with
D. |

To determine

The measure of interior angle

Explanation

**Given:**

A pentagon *ABCDE* with

Figure

**Formula used:**

Write the equation to calculate the sum of the measures of the interior angles of a polygon.

Here,

**Definition:**

If the angles of a pentagon are congruent, then the measures of the angles are same.

**Calculation:**

Calculate the sum of the measures of interior angles of a polygon.

Substitute

From the figure, the sum of interior angles of pentagon is,

Since, the angles of the pentagon are congruent then,
