Question:
If the ratio of corresponding sides of two similar triangles is \( 5:6 \), then the ratio of their perimeters is:
If the ratio of corresponding sides of two similar triangles is \( 5:6 \), then the ratio of their perimeters is:
Show Hint
In similar triangles, the ratio of corresponding sides, perimeters, and altitudes remains the same, but the ratio of areas is the square of the side ratio.
