Answer 1

Answer:

Step-by-step explanation:

AB=AD so <ABD=<ADB=72  

<BDC=180-<ABD=180-72=108 ( cause A,D,C are on the same line)

<BAC=180-(<ABD+<ADB)=180- (72+72)=180-144=36

so <BCA=<BAC=36 cause AB=BC ( trg BAC is isosceles)

<BCD=<BCA=36 ( cause A,D,C are on the same line)

<CBD=180-(<BDC+<BCD)=180- (108+36)=180-144=36

so <CBD=<BCD=36 so  the trg BCD is isosceles
