Question

Pls answer the attached question

Answer 1

Answer:

when AD = BC

angle A is equal to angle B

Step-by-step explanation:

angle A and angle N are equal as they are alternative interior angles

Answer 2

Answer:

draw a diagonal ac  and then   AD=DC (given)

AB= CD (parallel lines)

∠A=∠C  ( opposite angle )

so by SAS rule ΔABD≅ΔBDC

so all all other parts are equal to each other (by C.P.C.T)

so ∠A=∠B
