Question

Use a paragraph proof to prove the same-side interior angles theorem.

Given: AB || CD

Prove: Same-side interior angles are supplementary

Answer 1

angle 2 + angle 3 =180 deg ---- Linear Pair ----- (I)
but
angle 2 = angle 6 ---- corresponding angles

so (I) can be written as
angle 6 + angle 3 = 180 degree

But angle 2 and angle 6 are same side interior angles
Hence proved
