Question

If triangle DEC congruent to triangle BEC, which is true by CPCTC?

Answer 1

The correct answer is the second one

Explanation:

Line BE and ED are congruent because they are the same length and E is the mid line.

Answer 2

second option is correct

Explanation:

By the given

ΔDEC≅ΔBEC

which means triangle DEC is congruent to triangle BEC

then by CPCTC (corresponding parts of congruent triangle are congruent)

there every side and angle of DEC will be equal to BEC

⇒BE= DE (by CPCTC)

hence second option is correct
