The vertices of δabc are a (1, 5), b (3, 9), and c (5, 3). the vertices of δdef are d (−3, 3), e (−2, 5), and f (−1, 2). which conclusion is true about the triangles? the ratio of their corresponding sides is 1: 3. they are congruent by the definition of congruence in terms of rigid motions. the ratio of their corresponding angles is 1: 3. they are similar by the definition of similarity in terms of a dilation.

They are similar by the definition of similarity in terms of a dilation

Step-by-step explanation:

Corresponding angles have the same measure and corresponding sides are proportional.

The triangles are therefore similar by the definition of similarity in terms of a dilation.

A is wrong, because the ratio of their corresponding sides is 1:2.  

B is wrong, because the triangles cannot be superposed on each other.

C is wrong, because the ratio of corresponding angles is 1:1.

They are similar by the definition of similarity in terms of dilation

i just took the test

this is not the answer this is just a question. is this middle school math?

step-by-step explanation:

graph them on a graphing calculator, press 2nd trace. select intersect. hit enter until it says answer. ti 84 works best
