In similar triangles, the ratio of corresponding sides are equal, and is known as the scale factor:

height

_{2}/height_{1}= 9/12 = 3/4So the ratio of base

_{2}/base_{1}is also 3/4. Since base_{1}= 9: base

_{2}/9 = 3/4Solve for base

What if you are asked:

A right triangle has a height of 4 and a base of 6. Another triangle which is similar to the first has a base of 10. What is the size of its height?

20/3

15

12/5

5/12

15/2

12/5

base2/base1 = height2/height1

6/10 = 4/height1

height1 = 4*(10/6) = 20/3
