Question

Find the correct option.

• A. ∆ABC $\sim$ ∆QPR
• B. ∆ABC $\sim$ ∆PQR
• C. ∆ABC $\sim$ ∆RPQ
• D. ∆ABC $\sim$ ∆RQP

Answer 1

The correct option is A ∆ABC $\sim$ ∆QPR

In ∆ABC and ∆PQR,

∠A = ∠Q = 50°

∠B = ∠P = 60°

∠C = ∠R = 70°

$\therefore$ ∆ABC $\sim$ ∆QPR (by AAA similarity criterion)
