CCSS.HSG.CO.B.6

A transformation that “turns” a figure about a fixed point at a given angle and a given direction.

• rotation
• translation
• reflection
• dilation

CCSS.8.G.A.3

CCSS.HSG.CO.A.5

A type of transformation where a figure is “flipped” over a line of symmetry. A reflection produces a mirror image of a figure.

• rotation
• translation
• dilation
• reflection
