Question

a right angle intersects a line at point m. which statement is true about angles 1 and 2? they are congruent. they are right angles. they are complementary. they are supplementary.

Explanation:

Step1: Recall the definition of complementary angles

Complementary angles are two angles whose sum is \(90^{\circ}\).

Step2: Analyze the relationship between angles 1 and 2

Since the right - angle is \(90^{\circ}\) and the sum of angles around a point on a line is \(180^{\circ}\), we have \(\angle1+\angle2 + 90^{\circ}=180^{\circ}\). Then \(\angle1+\angle2=180^{\circ}- 90^{\circ}=90^{\circ}\).

Answer:

They are complementary.
