Aim: What are transformations? Do Now:Write down a list of commands for Ms. Pacman to eat all of the dots. You may use the following:

Translation (direction & distance)

Rotation (degree)

Reflection (vertical or horizontal)Ms. Pacman may never be upside down

Oct 17­5:56 PM

Transformation: A change that occurs to a figure

Aim: What are transformations? Think ­ Pair ­ ShareFor each transformation, indicate whether the angle, size, and orientation changes or remains the same.  Put 'same' or 'change' in each box:

translation

rotation

reflection

angles size orientation

dilation

same same same

same same same

same same change

same change same

unable to bend or be forced out of shape

Rigid Motion:  A transformation that preserves distance and angle measure
