Question

two triangles abc and pqr are drawn based on simi larity criteria​

Answer 1

In ∆ABC and ∆PQR, AB/PQ = BC/QR ⇒ AB/BC = PQ/QR Angle formed by sides AB and BC is ∠B Angle formed by sides PQ and QR is ∠Q ∴ ∠B = ∠Q is essential for similarity of two triangles. thus ∠B = ∠Q AB/BC = PQ/QR ∴ ∆ABC ~ ∆PQR (SAS similarity theorem)Read more on Sarthaks.com - https://www.sarthaks.com/759414/two-triangles-abc-and-pqr-pq-bc-qr-for-similarity-of-two-triangles-which-angles-should-equal
