Question

Prove that the ratio of the areas of two similar triangles is equal to the square of the ratio of their corrosponding sides?​

Answer 1

Answer:

So we can draw a perpendicular AD from A to BC and PS from P to QR. As two angles are equal so the third angle of both triangles should also be equal. Hence we can say the ratio of the areas of two similar triangles is equal to the ratio of the square of their corresponding sides.
