The vertices of triangle ABC are A (1,5), B (3,9), and C (5,3). The vertices of triangle DEF are D (-3,3), E (-2,5), and F (-1,2). Which conclusion is true about the triangles? A. The ratio of their corresponding sides is 1:3.

B. They are congruent by definition of congruence in terms of rigid motions.

C. The ratio of their corresponding angles is 1:3.

D. They are similar by definition of similarity in terms of a dilation.

Hurry and answer this! circle x with a radius of 6 units and circle y with a radius of 2 units are shown which steps would prove the circles similar? translate the circles so they share a common center point, and dilate circle y by a scale factor of 4. translate the circles so the center of one circle rests on the edge of the other circle, and dilate circle y by a scale factor of 4. translate the circles so they share a common center point, and dilate circle y by a scale factor of 3. translate the circles so the center of one circle rests on the edge of the other circle, and dilate circle y by a scale factor of 3
