Question

if triangle ABC is congruent to triangle DEF angle B is 50 ° find angle Dand F​

Answer 1

Step-by-step explanation:

heya

here is ur answer

given :- ∆ABC is congruent to ∆DEF

so by CPCT

<A= <D

< B = <E

<C = <F

so in ∆ABC

<A = 50°

<C = <F =60°

<B= ?

v all know that sum of interior angles of a triangle is equal to 180°

so

<A+ <B + <C = 180°

50° +. <B + 60° = 180°

<B + 110° = 180°

<B = 180° - 110°

<B = 70°

hope this helps u
