Question

use triangles to find the sum of the interior angle measures of the polygon. the sum of the interior measures of the polygon is

Explanation:

Step1: Determine the number of triangles

A quadrilateral can be divided into 2 triangles.

Step2: Calculate the sum of interior angles

Since the sum of interior angles of a triangle is \(180^{\circ}\), for 2 triangles, the sum is \(2\times180^{\circ}\).
\(2\times180^{\circ}=360^{\circ}\)

Answer:

\(360\)
