Given: adĀÆĀÆĀÆĀÆĀÆ is an altitude. prove: ab2+ac2=cb2 right triangle a b c with right angle a. point d lies on side b c and segment a d is drawn. angle a d c is a right angle. drag and drop a reason into each box to correctly complete the two-column proof. statement reason adĀÆĀÆĀÆĀÆĀÆ is an altitude, and ā bac is a right angle. given ā adb and ā adc are right angles. definition of altitude ā bacā
ā bda ? ā bacā
ā adc ? ā bā
ā b ? ā cā
ā c reflexive property of congruence ā³abcā¼ā³dba ? ā³abcā¼ā³dac aa similarity postulate abbd=cbab ? ab2=(cb)(bd) cross multiply and simplify. acdc=cbac polygon similarity postulate ac2=(cb)(dc) cross multiply and simplify. ab2+ac2=ab2+(cb)(dc) addition property of equality ab2+ac2=(cb)(bd)+(cb)(dc) substitution property of equality ab2+ac2=(cb)(bd+dc) ? bd+dc=cb segment addition postulate ab2+ac2=cb2 substitution property of equality
