Question

triangle ABC congruent to triangle DEF,angle a=30 degress angleb=80degress then find f​

Answer 1

Answer:

Here is your answer..

Given ∆ABC congruent to ∆DEF

By theorem 8.6 of similar triangles of class 10

Angle A=Angle = D

Angle B=Angle E

Angle C=Angle F

So, A+B+C=180

30+80+c = 180

110+c=180

C = 180-110=70.

:. Angle F = 70°...
