Question

If ∆ ABC~∆PQR and AB:PQ =5:7 then find A(∆ABC) :A (∆PQR) ​

Answer 1

Answer:

In △PQR using angle sum property of triangle

∠P+∠Q+∠R=180

∘

80

∘

+40

∘

+∠R=180

∘

⇒∠R=180

∘

−120

∘

=60

∘

Now △PQR≅△ABC

As corresponding parts of congruent triangle are equal

∴AB=PQ=5cm and ∠C=60
