A triangle undergoes several transformations and results in a congruent figure.
Which of the following was NOT a possible transformation?
(A) A rotation 90 degrees CCW about the origin
(B) A translation up 2 units and left 5 units.
(C) A dilation with a scale factor of 2
(D) A reflection across the y-axis
C.
Dilations are not a rigid transformation. Rigid = congruent shape.
