Use the conditional statement to draw a conclusion about ∠B.
m∠B=90^(∘)
Practice makes perfect
The Law of Detachment requires us to identify the hypothesis and conclusion of the given conditional statement. Here, we have a hypothesis that we are given a right angle. The conclusion that follows is that the measure of the angle is 90^(∘). Thus, if we are given a right angle, we can conclude by the law of detachment that the angle measures 90^(∘).
Given:& ∠B is a right angle.
Valid Conclusion:& m∠B = 90^(∘)
