How to show opposite sides on a parallelogram are congruent
Marta_Voda [28]

Answer:

I am attaching a image to understand my proof.

Step-by-step explanation:

PROVE:-

AB = DC

AD = BC

∠ ABD = ∠ BDC        (alternate angles are equal )

∠ DBC = ∠ ADB         (alternate angles are equal )

∴ Δ ADB ≅ Δ CBD     ( by ASA rule )

DC = BA                       ( corresponding sides of ≅ Δ )

AD = CB                        ( corresponding sides of ≅ Δ )

Hence it is proved that opposite sides of parallelogram are congruent )
