Transformation

• Translation is a way of transforming in a direction without changing the shape or size
• A translation flipped across a line of symmetry is called a reflection
• Point symmetry is when a figure is rotated 180 degrees around a point
• The center is called the point of symmetry
• Rotation is when the figure keeps it's shape and size but is rotated a certin amount of degrees
• An operation that combines two transformations is called a composite transformation

Similarity

• An enlarged or reduced figure is similar to the original figure
• The symbol for similarity is "∼"
• (Triangles Only!) If the ratios of the side are equal then it is similar
