Question

Classify triangle BCD based on side lengths, given:

AB = 5
ED = 3
BC = 8
FE = 2.5
AD = 7

Answer 1

BCD is an isosceles triangle

Answer 2

AB = BE = 5

BD = BE + ED = 5 + 3 = 8

BC = 8

BD = BC

CD = 5 which is not equal to 8.

Triangle BCD has exactly 2 congruent sides.

Answer: Triangle BCD is isosceles.
