Question

to show how aas follows from the definition of congruence, answer the following question. what rigid transformation maps △abc → △def? (1 point) rotation translation reflection dilation

Explanation:

Step1: Recall rigid - transformation types

Rigid transformations include translation, rotation, reflection. Dilation is not a rigid - transformation as it changes the size.

Step2: Analyze the orientation of triangles

By observing the orientation of $\triangle A''B''C''$ and $\triangle DEF$, we can see that the shape needs to be turned. Translation just moves the figure without turning it, and reflection flips the figure. Rotation is the transformation that turns a figure around a fixed point. Since the orientation of $\triangle A''B''C''$ needs to be adjusted to match $\triangle DEF$, rotation is the correct rigid transformation.

Answer:

rotation
