Which set of side lengths shows similar triangles?

a) Triangle ABC: 40, 20, 50; Triangle XYZ: 10, 12.5, 10

b) Triangle ABC : 110, 80, 60; Triangle XYZ: 6, 8, 5.5

c) Triangle ABC : 30, 40, 60; Triangle XYZ: 40, 30, 90

d) Triangle ABC : 32, 20, 32; Triangle XYZ: 10, 16, 16

Answer 1

The answer looks like D, because of the two congruent angles, and the smaller one. Also if you look at it 10, 16, 16 multiplied by two is 20, 32, 32. The answer is D.
