Question

plzz answer this question​

Answer 1

Answer:given that AB parallel to DC and AD parallel to BC such that it gives us that it is a parallelogram and it is property that opposite side of the parallelogram are equal so AB=DC and AD=BC

Step-by-step explanation:

Answer 2

Answer:

Given:ab||cd

ad||bc

To prove:ab=cd

ad=bc

Construct:Join AC

Proof:

In triangle abc and triangle adc:

Angle cab = angle acd (interior opposite angles)

Angle cad = angle acb (interior opposite angles)

AC = AC (Common)

Therefore by asa similarity criteria :

Triangle ABC = Triangle ADC

Therefore ab=cd (by cpct)

bc=ad (by cpct)

Hence proved
