Question

It is given the triangle ABC= triangle FDE and AB=4cm,Angle B=40degre and angle E=60degree
then which of the following is true,?​
A)DE=4cm angle A=80degre
B)DF=4cm angle A=80degre
C)DE=4cm angle C=80degre
D)DF=4cm angle C=80degre​

Answer 1

Answer:

(b)DF=4cm and angle A=80degree

Step-by-step explanation:

The following can be true based on the conditions given about the congruent triangles:

1. AB=FD=4cm

2. ∠E=∠C= 60 degree

3.∠B=∠D=40 degree

4.Therefore angle A is 80 degree (sum of angles of a triangle=180 degree)

5.∠A=∠F=80 degree
