Question

2-1.
It is given the triangleABC=triangleFDE and AB=4 cm, B = 40° and angleE= 60°
then which of the following is true.
(A) DE = 4 cm, angleA=80°cm
(B) DE=4 cm, angleC=80°
(C) DF = 4 cm, angleA=80°
(D) DF = 4 cm, angleC=80°​

Answer 1

Answer:

Given-

ΔABC = ΔFDE

AB = 4cm

B = 40°

E = 60°

Giving Answer -

Two triangles are congruent if their corresponding sides are equal in length and their corresponding angles are equal in size.
