All birds have feathers. a. b. Two angles are supplementary if they are a linear pair. a. All birdshavefeathers. EXAMPLE 1 Rewrite a statement in if-then form Rewrite the conditional statement in if-then form. SOLUTION First, identify the hypothesisand the conclusion. When you rewrite the statement in if-then form, you may need to reword the hypothesis or conclusion. If an animal is a bird, then it has feathers.
Two angles are supplementaryif they are a linear pair. b. EXAMPLE 1 Rewrite a statement in if-then form If two angles are a linear pair, then they aresupplementary.
1. All 90° angles are right angles. ANSWER If the measure of an angle is 90°,then it is a right angle 2. 2x + 7 = 1, becausex = –3 ANSWER If x= –3, then 2x + 7 = 1 for Example 1 GUIDED PRACTICE Rewrite the conditional statement in if-then form.
