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.
Answer
Explanation:
Step1: Recall angle - sum property
The right - angle and angles 1 and 2 form a straight - line. The sum of angles on a straight - line is 180°. Let the right - angle be 90°. So, ∠1+∠2 + 90°=180°.
Step2: Solve for ∠1 + ∠2
Subtract 90° from both sides of the equation ∠1+∠2 + 90°=180°. We get ∠1+∠2=180° - 90° = 90°.
Answer:
They are complementary.
