Identifying Rigid Transformations

Front

What is a rigid transformation?

Back

A transformation that preserves the shape and size of a figure, including translations, rotations, and reflections.

Front

What type of transformation is a rotation?

Back

A rigid transformation that turns a figure about a fixed point at a given angle and direction.

Front

What is translation in geometry?

Back

A transformation that moves every point of a figure the same distance in a given direction.

Front

What does reflection mean in geometry?

Back

A transformation that flips a figure over a line, creating a mirror image.

Front

What is the difference between rotation and reflection?

Back

Rotation turns a figure around a point, while reflection flips it over a line.

Front

True or False: A dilation is a rigid transformation.

Back

False. A dilation changes the size of a figure.

Front

How do you identify a translation?

Back

By observing the movement of a figure in a straight line without changing its shape or size.

Front

What is the effect of a 180-degree rotation on a figure?

Back

It turns the figure upside down.

Front

If a figure is translated 5 units right and 3 units up, what is the new position of a point (2, 2)?

Back

The new position is (7, 5).

Front

What is the result of reflecting a point (3, 4) across the x-axis?

Back

The new point is (3, -4).
