Question

angles 1 and 2 form a right angle. which word describes their measures? linear congruent complementary supplementary

Explanation:

To determine the relationship between angles 1 and 2, we use the definition of angle pairs:

• Linear pair: Angles forming a straight line (sum to \(180^\circ\)).
• Congruent: Angles with equal measure.
• Complementary: Angles whose sum is \(90^\circ\) (a right angle).
• Supplementary: Angles whose sum is \(180^\circ\).

Since angles 1 and 2 form a right angle, their sum is \(90^\circ\), so they are complementary.

Answer:

complementary (the option corresponding to "complementary")
