Question

determine which geometric transformation is illustrated in the diagram shown below.
a. reflection
b. translation
c. refraction
d. rotation
e. dilation

Explanation:

A reflection flips a figure over a line. A translation slides a figure. Refraction is a physics - related concept not a geometric transformation here. A rotation turns a figure around a point. A dilation changes the size of a figure. The given triangle appears to be turned around a point, which is the characteristic of rotation.

Answer:

D. rotation
