Question

Omar thinks that If two angles of one triangle are congruent to two angles of another triangle, then the triangles are similar. To show this, he drew the figure below. 

Which set of transformations maps AABC to ADEC and support Omar's thinking?

 A. a rotation of 180° clockwise about point followed by a dilation with a center of point C and a scale factor of 2

 B. a rotation of 180° clockwise about point C followed by a dilation with a center of point C and a scale factor of 1/2

 C. a rotation of 180° counter-clockwise about point C followed by a dilation with a center of point C and a scale factor of 3

 D. a rotation of 180° counter-clockwise about point followed by a dilation with a center of point C and a D. scale factor of 1/3

Answer 1

A rotation of 180 degree clockwise about point C followed by a dilation with a center of point C and a scale factor of 2
