Geometry Reflections

Front

True or False: Rigid motions preserve angle measure.

Back

True

Front

Reflect the point (2, -4) over the y-axis.

Back

(-2, -4)

Front

Which transformation is NOT a rigid motion (the size changes)?

Back

dilation

Front

A rigid motion creates figures that are ____________.

Back

congruent

Front

Find K' if the figure is reflected across the x-axis: (1, -4)

Back

(1, 4)

Front

What is a rigid motion?

Back

A transformation that preserves distance and angle measures.

Front

What happens to the coordinates of a point (x, y) when reflected over the y-axis?

Back

The coordinates become (-x, y).

Front

What happens to the coordinates of a point (x, y) when reflected over the x-axis?

Back

The coordinates become (x, -y).

Front

What is the difference between rigid motion and non-rigid motion?

Back

Rigid motion preserves size and shape; non-rigid motion changes size or shape.

Front

If a triangle is reflected over a line, what can be said about the original triangle and the reflected triangle?

Back

They are congruent.
