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 How was this figure translated? We will also learn how to translate figures on a coordinate plane!

Translation

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! How was this figure reflected?

Reflection

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

Rotation

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

Dilation A dilation is a transformation in which a figure GROWS or SHRINKS. The size of the figure changes, but the shape doesn’t!

Dilation How was this figure dilated? We will also learn how to dilate figures on a coordinate plane!

Dilation
