Answer 2

• Triangle AOB congruent to Triangle DOC (given)
• So, angle BAO = angle ODC
• While consedering the lines AB and CD and AD as the transversal these two angles forms the alternate interior angles
• Similarly taling the lines AB and CD and BC as the transversal angle C = angle B
• Therefore as the pairs of alternate interior angles are equal the two lines AB and CD are parallel....
