arrange in increasing size order to test corresponding sides
RI = 7.5
TR = 10
TI = 12.5
now if all sides are related by the same scale factor, they are similar
7.5/6 = 1.25
10/8 = 1.25
12.5/10 = 1.25
YES!! the corresponding sides are in the same ratio. They are similar with scale factor 1.25
One triangle has vertices A, B, and C. Another has vertices T, R, and I. Are the two triangles similar? If so state the similarity and the scale factor.
AB- 6
BC- 8
AC- 10
TR- 10
RI- 7.5
TI- 12.5
