8. जर ∆ABC~ ∆LMN आणण⦟A = 60° असल्र्यस ⦟L =?​

Answer»

ong>Given :-

  • ∆ABC~ ∆LMN .
  • ∠A = 60° .

To Find :-

  • ∠L = ?

Solution :-

we know that, when TWO ∆'s are SIMILAR ,

  • Corresponding sides of first ∆ = Corresponding sides of second ∆ .
  • Corresponding sides of first angles = Corresponding sides of second angles .

so,

→ AB / LM = BC / MN = AC / LN

and,

→ ∠A = ∠L , ∠B = ∠M, ∠C = ∠N .

therefore,

if ,

→ ∠A = 60°

hence,

→ ∠L = ∠A = 60° (Ans.)
