Question

exploring the sums of the angle measures in quadrilaterals
rectangle abcd has four right angles.

1. what is the sum of its angle measures?

Explanation:

Step1: Determine the measure of one angle

A right angle measures \(90^{\circ}\).

Step2: Calculate the sum of four angles

Since there are four right angles in rectangle \(ABCD\), the sum is \(4\times90^{\circ}\).

$$4\times90^{\circ}=360^{\circ}$$

Answer:

\(360^{\circ}\)
