rigid motions
What are the three main types of rigid motions?
Translation (sliding), Reflection (flipping), and Rotation (turning).
What do rigid motions preserve?
They preserve distance (lengths of sides) and angle measures.
What is the relationship between pre-image and image in a rigid motion?
The resulting image is always congruent to the original pre-image.
What is a "prime" in rigid motions?
An apostrophe used to label the new position of a point after transformation, called "A prime".
Is a dilation a rigid motion?
No. Dilations change the size of an object, whereas rigid motions keep size and shape constant.
