Rigid Transformations in the Coordinate Plane

Coordinate Rule:
270 degree Rotation (counterclockwise)

• (x,y) -> (x, -y)

• (x,y) -> (-y,x)

• (x,y) -> (-x, -y)

• (x,y) -> (y,-x)

Which of the following is NOT an Isometry?

• Translation

• Rotation

• Dilation

• Reflection

A function that takes points in a plane as an input and maps them to an output.

• Transfiguration

• Transformation

• Input Map

• Output Map

Translation Coordinate Rules

• (x,y) ->(y, x)

• (x,y) ->(x+h, y+k)

• (x,y) -> (-x, -y)

• (x, y) -> (-y, -x)
