Question

Verify that triangle ABC ~ triangle DEF. Find the scale factor of triangle ABC to triangle DEF.

Triangle ABC : BC = 18, AB = 15, AC = 12

Triangle DEF : EF = 12, DE = 10, DF = 8

Answer 1

The ratio of the sides of triangle DEF to triangle ABC is 2/3.

The factors used to reduce are 4, 5, and 6.
