Question

Prove that isosceles triangle ABC and BCD are congruent that is triangle triangle ABC is congruent to triangle BCD


Plz solve it urgently........​

Answer 1

Step-by-step explanation:

you can use the side, angle, side theorem to prove that triangle ABC is congruent to triangle DCB.

Given:

Line AB is congruent to line CD

Ling AB is parallel to line CD

Proof:

This gives something like this:

C D

---------\------------------- line CD

/ \ /

/ \ /

------------\---------------- line AB

A B

Since lines AB and CD are parallel, line BC becomes a transversal of the parallel lines.

Side 1: Given AB congruent to CD.

Angle: Angle ABC congruent to Angle BCD, alternate interior angles of a transversal through parallel lines are congruent.

Side 2: CB is congruent to CB, reflex property of congruent lines.

Therefore, triangle ABC is congruent to triangle DCB.
