If two similar triangles have a scale factor of 5:4, what is the ratio of their corresponding altitudes?

Answer 1

here
When you compare the ratios of the perimeters of these similar triangles, you also get 2 : 1. This leads to the following theorem. Theorem 60: If two similar triangles have a scale factor of a : b, then the ratio of their perimeters is a : b. Figure 2 Perimeter of similar triangles.

Answer 2

not sure what the question has to do with perimeters, but the scale factor applies to all linear dimensions. So the altitudes are also in the ratio 5:4

Answer 3

Since its given that the scale factor is 5:4 of similar triangles then the ratio of corresponding altitudes will also be 5:4. As when two triangles are similar their corresponding side, perimeter,altitudes have same ratio...
