What is a reflection in geometry?

Back

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

Front

What is a translation in geometry?

Back

A translation is a transformation that slides a figure from one position to another without changing its shape or orientation.

Front

What is a rotation in geometry?

Back

A rotation is a transformation that turns a figure around a fixed point at a certain angle.

Front

What are rigid transformations?

Back

Rigid transformations are movements of figures that preserve their shape and size, including translations, rotations, and reflections.

Front

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

Back

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

Front

What happens to the coordinates of a point when it is translated 3 units to the right and 2 units up?

Back

The new coordinates will be (x+3, y+2).

Front

If point X is in Quadrant I, where will it be after a 90-degree clockwise rotation?

Back

Point X will move to Quadrant IV.

Front

What is the effect of a 180-degree rotation on a point (x, y)?

Back

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

Front

How can you identify a reflection in a graph?

Back

Look for symmetry across a line; points will be equidistant from the line of reflection.

Front

What is the line of reflection?

Back

The line of reflection is the line over which a figure is flipped to create a mirror image.
