Question

In ????ABCD, side BC || side AD, sideAB≅sideDC If ∠A=72° then find the measures of ∠B, and ∠D.

Answer 1

Answer:

measures of ∠B, and ∠D 108°

Step-by-step explanation:

its given that in quadrilateral

BC ║ AD

=> ∠A + ∠B = 180°

& ∠C + ∠D = 180°

∠A = 72°

=> 72° + ∠B = 180°

=> ∠B = 108°

Now AB = DC

=> AB ║ DC    

∠A + ∠D = 180°

=> ∠D = 108°

measures of ∠B, and ∠D 108°
