Transformations - Warm Up

Front

What is a transformation in geometry?

Back

A transformation is an operation that moves or changes a shape in some way to create a new shape.

Front

What are the four main types of transformations?

Back

Translation, Reflection, Rotation, Dilation.

Front

What is translation?

Back

Translation is a transformation that slides a shape from one position to another without turning it.

Front

What is reflection?

Back

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

Front

What is rotation?

Back

Rotation is a transformation that turns a shape around a fixed point at a certain angle.

Front

What is dilation?

Back

Dilation is a transformation that changes the size of a shape but keeps its proportions the same.

Front

If a point (x, y) is translated 4 units left, what is the new point?

Back

(x-4, y).

Front

If a point (x, y) is reflected over the x-axis, what is the new point?

Back

(x, -y).

Front

If a point (x, y) is rotated 90 degrees clockwise around the origin, what is the new point?

Back

(y, -x).

Front

What is the scale factor in dilation?

Back

The scale factor is the ratio of the size of the new shape to the size of the original shape.
