Question

the figure AB = DE = 12, AC = DF = 6, BC = EF = 8

a) Are triangles ABC and DEF equal? How can we understand it?

1 score

b) If ∠A = x then what is ∠D ?

1 score

c) Write the matching angles of these triangles?​

Answer 1

Answer:

2. I think angle D is also x

Answer 2

Answer:

1. If all corresponding sides of both triangles are equal. Then both triangles are similar. Therefore, triangle ABC and triangle DEF are equal.

2. Since both triangles are equal. Therefore, there all corresponding sides and angles will be equal. Since, angle A and angle D are corresponding. Therefore, if angle A=x so, angle D=x

3. angle A = angle D

angle B = angle E

angle C = angle F
