triangle def is congruent to △ghj by the sss theorem. which rigid transformation is required to map △def onto △ghj? dilation reflection rotation translation

triangle def is congruent to △ghj by the sss theorem. which rigid transformation is required to map △def onto △ghj? dilation reflection rotation translation

Answer

Explanation:

Step1: Recall rigid - transformation properties

Rigid transformations preserve shape and size. Dilation is not a rigid - transformation as it changes the size. Reflection flips a figure over a line, rotation turns a figure around a point, and translation slides a figure.

Step2: Analyze the orientation of the triangles

The orientation of $\triangle DEF$ and $\triangle GHJ$ is the same. Reflection and rotation change the orientation of a figure. Since the orientation is unchanged and we need to move $\triangle DEF$ to $\triangle GHJ$, we use translation.

Answer:

translation
