given figure, ABCD is a quadrilateral in which AB || DC and
11. In the given fic
AD || BC
Prove that ZADC = LABC.​

Answer 1

Answer:

Given: ABCD is a quadrilateral and AB//DC and AD//BC.

To Prove that: angle ADC= angle ABC.

Construction: We draw a diagonal AC.

Proof: AB//DC and AD//BC (Given)

ABCD is a parallelogram and opposite angle of parallelogram are equal.

So, angle ADC=angle ABC
