Kelsey uses the similarity statement Triangle R S T is similar to triangle R U V to describe the triangles below. Triangle R U V. Side V R is 4 centimeters, R U is 1.5 centimeters, and V U is 2.7 centimeters. Triangle R S T. Side R S is 3.0 centimeters, R T is 8.0 centimeters, and S T is 5.4 centimeters. Which best describes the accuracy of her statement? Accurate. Each pair of sides corresponds with a common ratio of 2. Accurate. The description of each triangle begins at the same vertex. Inaccurate. In the order listed, the ratio between each pair of sides is different. Inaccurate. The description of the triangles in the similarity statement moves clockwise in one triangle and counterclockwise in the other triangle.
