question
triangle ijk and triangle idk are drawn below. use the dropdown boxes below to determine a transformation that maps triangle ijk onto triangle idk.

Explanation:

Step1: Observe common vertex

Vertex $I$ is common to both $\triangle IJK$ and $\triangle IDK$.

Step2: Analyze side - change

Side $IJ$ is mapped to side $ID$. This indicates a rotation about point $I$.

Step3: Determine rotation direction

By visual inspection, the rotation is clock - wise about point $I$ to map $\triangle IJK$ onto $\triangle IDK$.

Answer:

A clock - wise rotation about point $I$
