Answer 1

By SAS rule

Explanation:

Required to Prove

ABC is congruent to DEC

Given

C is midpoint of AD and BE

As C is the midpoint of both line segments

AC=CD

BC=CE

and ∠ACB=∠DCE(Vertically opposite angles)

⇒By SAS(side-AC and DC, angle-∠ACB,∠DCE,side-BC and EC) congruency rule

triangle ABC is congruent to triangle DEC
