Unit 3 Test Review

Front

What is a rigid motion?

Back

A transformation that preserves side length and angle measure.

Front

What happens to a figure during a translation?

Back

The figure moves from one location to another without changing its shape or size.

Front

How do you find the image of a point after a translation by a vector?

Back

Add the vector components to the coordinates of the point.

Front

What is the result of rotating a figure 270° counterclockwise around the origin?

Back

The figure's position changes based on the angle of rotation.

Front

What is the definition of a transformation in geometry?

Back

A change in the position, size, or shape of a figure.

Front

What is the difference between reflection and rotation?

Back

Reflection flips a figure over a line, while rotation turns it around a point.

Front

What does it mean to reflect a figure across the y-axis?

Back

The x-coordinates of the points are negated, while the y-coordinates remain the same.

Front

What is the effect of a 90° counterclockwise rotation on a point (x, y)?

Back

The new coordinates will be (-y, x).

Front

What is the capital of France?

Back

Paris.

Front

What is the purpose of identifying transformations in geometry?

Back

To understand how figures change and relate to one another.
