Transformations Review

Front

In a translation, if a point moves left 5 units, what is the transformation applied?

Back

The transformation applied is a translation to the left by 5 units.

Front

What is the scale factor if the point (8, 12) is dilated to (2, 3)?

Back

The scale factor is ¼.

Front

Using the y-axis as the mirror line, what type of transformation is this?

Back

This is a reflection.

Front

What does dilation mean in geometry?

Back

Dilation is a transformation that alters the size of a figure, either enlarging or reducing it.

Front

If a shape is enlarged by a scale factor of 2, what happens to its dimensions?

Back

All dimensions of the shape are multiplied by 2.

Front

What is the result of a reflection over the x-axis for the point (3, 4)?

Back

The result is the point (3, -4).

Front

What is the difference between a translation and a rotation?

Back

A translation moves a shape without changing its orientation, while a rotation turns a shape around a fixed point.

Front

If a shape is reduced by a scale factor of ½, what happens to its area?

Back

The area is reduced to ¼ of the original area.

Front

What is the effect of a translation that moves a point up 5 units?

Back

The y-coordinate of the point increases by 5.

Front

What is the definition of a transformation in geometry?

Back

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