Rigid Transformation Review

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 is the effect of a reflection on a geometric figure?

Back

A reflection flips a figure over a line, creating a mirror image of the original figure.

Front

How does a translation affect the coordinates of a point?

Back

A translation moves a point a certain distance in a specified direction, changing its coordinates accordingly.

Front

What is the result of rotating a point 90° clockwise about the origin?

Back

The coordinates of the point (x, y) become (y, -x) after a 90° clockwise rotation.

Front

What happens to the coordinates of a point when it is rotated 180° about the origin?

Back

The coordinates of the point (x, y) become (-x, -y) after a 180° rotation.

Front

What is the image of a point after a translation of 3 units left and 9 units down?

Back

If the original point is (x, y), the new coordinates will be (x - 3, y - 9).

Front

How do you determine the image of a point after a rotation of 270° clockwise?

Back

To find the image of a point (x, y) after a 270° clockwise rotation, the new coordinates will be (-y, x).

Front

What is the difference between a rotation and a reflection?

Back

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

Front

What is the rule for reflecting a point across the x-axis?

Back

The coordinates of the point (x, y) become (x, -y) after reflection across the x-axis.

Front

What is the rule for translating a point (x, y) 5 units up and 2 units right?

Back

The new coordinates will be (x + 2, y + 5) after the translation.
