Question

what single transformation was applied to triangle a to get triangle b?
choose 1 answer:
a translation
b rotation
c reflection
d dilation

Explanation:

Translation moves a shape without rotation or reflection. Rotation turns a shape around a point. Reflection flips a shape over a line. Dilation resizes a shape. Observing the triangles, triangle B is a mirror - image of triangle A. So, reflection is the transformation.

Answer:

C. Reflection
