Compose Transformations

What is a sequence of transformations?

• A transformation that includes 1 translation, 1 reflection, and 1 rotation

• Two or more translations, reflections, or rotations that map a preimage to its image

• A graph that includes an image and a preimage

• The coordinates of the vertices of an image and a preimage
