Transformations

Define rotation.

A transformation in which a plane figure turns around a fixed center point

Which transformation will result in an image which is similar, but not congruent, to the pre-image?

Dilation

What is the shape called after the transformation?

Image

Which of the following describes the movement of a figure that is translated according to the rule below? (x,y) -> (x-3, y+7)

Left 3 units, Up 7 units

What is the original shape called?

Pre-image

A figure is located entirely in the second quadrant. If it is reflected over the x-axis, in which quadrant will its image lie?

Quadrant 3

A figure is located entirely in the third quadrant. If it is reflected over the y-axis, in which quadrant will its image lie?

Quadrant 4

Which transformation occurs when the fan blades turn?

Rotation

Define transformation.

a general term for four specific ways to manipulate the shape of a point, a line, or shape.

Define reflection.

a transformation in which each point of the original figure has an image that is the same distance from the line of reflection as the original point but is on the opposite side of the line.
