Combination of Rigid Motion Transformations

A transformation that preserves distances and angle measurements is called a(n):

• Dilation

• Rigid motion

• Heterogeneous transformation

• Alteration

Answer explanation

A transformation that preserves distances and angles is known as a rigid motion. This includes translations, rotations, and reflections, which maintain the shape and size of geometric figures.

Which of the following is NOT a rigid motion?

• Dilation

• Translation

• Rotation

• Reflection

Answer explanation

Dilation is not a rigid motion because it changes the size of a figure, while translation, rotation, and reflection preserve the shape and size of the figure.

Match each of the following descriptions with the correct transformation

• Rotation

• A rigid motion that creates a mirror image on the opposite side of a line or point

• A rigid motion that shifts a figure by a certain direction and distance.

• Translation

• A transformation that enlarges or shrinks an image while maintaining a similar image

• Reflection

• A rigid motion that spins an image about a point
