How to write a rule

(x,y)→(x+n,y+n)

Translation

Type of rigid transformation that makes the shape go up,down,left,right

Dilation

Type of transformation (not rigid) that involves the changing of object size

Scale Factor

The factor of which a shape is dilated by

Rigid Transformation

Transformation that doesnt change shape or size (Eg translation)

Rotation

Rigid transformation that turns a figure around a fixed point against a fixed angle

Reflection

rigid transformation that flips a shape over a line (eg y=x, y-axis, x-axis,y=-x, etc)

y=x

line that forms diagonally, going from -x,-y to x,y quadrants

y=-x

opposite of y=x, goes diagonally from -x,y quadrants to x,-y quadrants

center

center point of a shape

center of dilation

center of which a figure is dilated/scaled up or down by

center of rotation

center by which a figure is rotated by (eg, the origin)
