Rigid Transformations Practice

Front

What is a rigid transformation?

Back

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

Front

What happens to a point when it is reflected across the x-axis?

Back

The y-coordinate of the point changes sign, while the x-coordinate remains the same.

Front

What are the coordinates of point A(1, 3) after a 90° clockwise rotation?

Back

(3, -1)

Front

True or False: A point remains the same distance from a line of symmetry when reflected across it.

Back

True

Front

What is the effect of a reflection across the y-axis on the point B(4, 5)?

Back

The new coordinates will be B'(-4, 5).

Front

What does it mean for transformations to preserve angle measurements?

Back

It means that the angles between lines or segments in the figure remain unchanged after the transformation.

Front

What is the result of reflecting a point across the line y = x?

Back

The x and y coordinates of the point are swapped.

Front

What is the difference between translation and rotation?

Back

Translation moves a figure without changing its orientation, while rotation turns a figure around a fixed point.

Front

What is the sequence of transformations: Reflect across the x-axis and then rotate -90 degrees around the origin?

Back

This sequence first flips the figure over the x-axis and then rotates it 90 degrees clockwise.

Front

What does it mean for transformations to preserve parallel lines?

Back

It means that if two lines are parallel before the transformation, they will remain parallel after the transformation.
