If PQ = 10 cm, find AB Since the ratio of the corresponding sides of similar triangles is same as the ratio of their perimeters. ∴ ∆ABC ~ ∆PQR `\Rightarrow \frac{AB}{PQ}=\frac{BC}{QR}=\frac{AC}{PR}=\frac{36}{24}` `\Rightarrow \frac{AB}{PQ}=\frac{36}{24}\Rightarrow\frac{AB}{10}=\frac{36}{24}` `\Rightarrow AB=\frac{36\times 10}{24}cm=15cm` Concept: Similarity of Triangles Is there an error in this question or solution? |
