Identify the Type of Transformation

Front

What is a transformation in geometry?

Back

A transformation in geometry refers to the movement of a shape in a plane. This can include changes in position, size, and orientation.

Front

Define translation in geometry.

Back

Translation is a transformation that moves a shape from one location to another without changing its size, shape, or orientation.

What is a reflection?

Back

A reflection is a transformation that flips a shape over a line, creating a mirror image.

Front

Explain rotation in geometry.

Back

Rotation is a transformation that turns a shape around a fixed point, known as the center of rotation, by a certain angle.

What is dilation?

Back

Dilation is a transformation that changes the size of a shape but keeps its proportions the same, either enlarging or reducing it.

How does a translation affect the coordinates of a point?

Back

In a translation, the coordinates of a point (x, y) change to (x + a, y + b), where 'a' and 'b' are the horizontal and vertical shifts, respectively.

What happens to a shape during a reflection over the x-axis?

Back

When a shape is reflected over the x-axis, the y-coordinates of its points change sign, resulting in a mirror image across the x-axis.

Front

Describe the effect of a 90-degree rotation counterclockwise on a point (x, y).

Back

A 90-degree rotation counterclockwise transforms the point (x, y) to (-y, x).

What is the center of dilation?

Back

The center of dilation is a fixed point in the plane about which a shape is enlarged or reduced during a dilation transformation.
