Assertion: In the A ABC, AB= 24 cm, BC=7 cm and AC= 25cm, then \( △\text{ABC} \) is a right angle triangle.
Reason: The ratio of the areas of two similar triangles is equal to the square of the ratio of their corresponding sides. Ans. We know that the ratio of the areas of two similar triangles is equal to the.

1 Both assertion (A) and reason (R) are true and reason (R) isthe correct explanation of assertion (A).
