Question

Two triangles are similar, and the ratio of the corresponding sides is 1:5, and which of the following is true?

a. Their corresponding sides are congruent.

b. Their corresponding angles are in a ratio of 1:5

c. Their areas have a ratio of 1:5.

d. their perimeters are in a ratio of 1:5

Answer 1

d. their perimeters are in a ratio of 1:5

Explaination

A is untrue because the sides have the ratio of 1:5, explained in the quastion, so they are not equal/congruent.

B is untrue because the angles are the same in both triangles because the triangles are similar, mentioned in the question.

C is untrue because the ratio of area is squared to the ratio of the perimeter, so the actual areas would be 1:25.

Answer 2

c
