# Geometry: Transformations Geometry: Transformations MCC1: a. Describe three-dimensional figures formed by translations and rotations of plane figures through space.

Essential Questions: How can the coordinate plane help me understand properties of reflections, translations and rotations? What is the relationship between reflections, translations and rotations?

Transformations A transformation is a way to move all the points on a figure. Types of Transformations: Translations Reflections

Rotations Dilations Translation A translation is a transformation that SLIDES a figure across a plane or

through space. All points of the figure move the same distance in the same direction. Translation We will also learn how to translate figures on a

Reflection A reflection is a transformation in which a figure is FLIPPED across a line. The line is called a line of reflection. After a figure is reflected, it looks like a

mirror image of itself. Reflection We will also learn how to reflect figures on a coordinate plane!

A rotation is a transformation that TURNS a figure about a point. Rotation

Rotation How was this figure rotated? We will also learn how to rotate figures on a coordinate plane!

Dilation A dilation is a transformation in which a figure GROWS or SHRINKS. The size of the figure changes, but the shape doesnt!

Dilation We will also learn how to dilate figures on a coordinate plane!
