Question

Ratio of areas of two triangle

Answer 1

The ratio of the areas of two similar triangles is equal to the square of ratio of their corresponding sides.

Answer 2

When two triangles are similar, the reduced ratio of any two corresponding sides is called the scale factor of the similar triangles. In Figure 1 , Δ ABC∼ Δ DEF. Figure 1 Similar triangles whose scale factor is 2 : 1. The ratios of corresponding sides are 6/3, 8/4, 10/5.
