Final answer:
The law of detachment is used to draw a conclusion from two given statements in a conditional statement format. In this case, the conclusion is that angle E is congruent to angle F.
Step-by-step explanation:
The law of detachment is used to draw a conclusion from two given statements in a conditional statement format. In this case, the two given statements are:
1. If two angles are complementary, then the sum of the measures is 90°.
2. Angle E and angle F are complementary.
Using the law of detachment, we can conclude that angle E is congruent to angle F.
