# A polygon has an angle sum of 360° and each angle measures 90°. What is the polygon?

A closed shape having sides and vertices is known as a polygon. If a polygon has interior angles and sides are equal, it is known as a regular polygon.

## Answer: Rectangle and square are polygons that have an angle sum of 360° and each angle measures 90°.

Let's solve it step by step.

**Explanation:**

The sum of interior angles of a polygon with 'n' sides is: (2n - 4) × 90°

⇒ (2n - 4) × 90° = 360°

2n - 4 = 4

2n = 4 + 4

2n = 8

n = 4

Here, a rectangle and a square are polygons that have an angle sum of 360°, and each angle measures 90°

Let's get an idea with the given figure shown below.
