With the information given below, determine how the triangles can be shown to be similar. m = 9 cm n = 12 cm o = 15 cm p = 12 cm q = 16 cm r = 20 cm

There's no diagram but I'm assuming that

1 triangle has sides of 9, 12 and 15 and the

other triangle has sides of 12, 16 and 20

Comparing the corresponding sides

(12 / 9) (16 / 12) and (20 / 15)

we see that each of those fractions equals 1.33333333 so,

the triangles are similar.
