Question

1. here are 4 triangles that have each been transformed by a different transformation. which transformation is not a rigid transformation? (and can you identify the others by what kind of transformation they are?) a. b. c. d. he started reflecting triangle cde across line m. so far, he knows the image of d is d and the image of e. then lightly shade in triangle and compass moves, determine the location of c.

Explanation:

Step1: Recall rigid - transformation definitions

Rigid transformations include translations, rotations, and reflections, which preserve shape and size.

Step2: Analyze option a

This appears to be a translation. The triangle has moved from one position to another without changing shape, size, or orientation in a non - flipped way. It is a rigid transformation.

Step3: Analyze option b

This is a reflection. The triangle is flipped over a line. Since reflection preserves shape and size, it is a rigid transformation.

Step4: Analyze option c

This is a rotation. The triangle has been turned around a point. Rotation preserves shape and size, so it is a rigid transformation.

Step5: Analyze option d

This is a dilation. The triangle has changed in size (it has been made larger or smaller). Dilation is not a rigid transformation as it does not preserve size.

Answer:

d
