Rigid Transformation Test

Front

What is a rigid transformation?

Back

A rigid transformation is a transformation that preserves the shape and size of a figure, meaning the figure remains congruent to its original form.

Front

What are the types of rigid transformations?

Back

The types of rigid transformations include translations, rotations, and reflections.

Front

What happens to the coordinates of a point when it is reflected over the Y-axis?

Back

The X-coordinate of the point changes sign, while the Y-coordinate remains the same.

Front

What is the result of rotating a point 90 degrees counterclockwise around the origin?

Back

The new coordinates (x, y) become (-y, x).

Front

What is the quadrant of a point with coordinates (-3, -4)?

Back

The point is in Quadrant III.

Front

Define 'image' in the context of transformations.

Back

An image is the new figure that results from a transformation applied to a pre-image.

Front

What does it mean for two figures to be congruent?

Back

Two figures are congruent if they have the same size and shape.

Front

How do you perform a 180-degree rotation around the origin?

Back

To perform a 180-degree rotation, change the signs of both the x and y coordinates of the point.

Front

What is the effect of a translation on a figure?

Back

A translation moves every point of a figure the same distance in the same direction without changing its shape or size.

Front

What is the relationship between corresponding sides of congruent figures?

Back

Corresponding sides of congruent figures are equal in length.
