ac=bd to proof ❓❓❓❓❓❓❓❓❓❓❓❓❓❓❓❓❓❓❓❓❓❓❓❓❓❓❓❓❓❓❓

Answer 1

In triangle BCD and triangle DAB
Angle ADB = angle CBD (alternate interior angles ,as Ab || Dc and BD is transversal)

BD = BD (Common)
angle CDB = angle ABD (alternate interior angles,as Ab||dc and BD is transversal)

By SAS TRIANGLE BCD IS CONGRUENT TO TRIANGLE DAB
AC = BD BY CPCT

Answer 2

Soln:- In triangle (ABC and BCD)
AB=CD(opposite side)
BC=BC(Common)
angle C=angle B
so Triangle ABC congruent Triangle BCD(By S-A-S congruence)
so AC=BD (by cpct)
