Rigid Transformation Review

Front

What is a translation in rigid transformations?

Back

A translation is a transformation that moves every point of a figure the same distance in the same direction.

Front

What happens to the coordinates (x-4, y) during a translation?

Back

The point moves 4 units left.

Front

What is a reflection in rigid transformations?

Back

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

Front

What is a rotation in rigid transformations?

Back

A rotation is a transformation that turns a figure about a fixed point at a given angle and direction.

Front

What is the result of a 90-degree clockwise rotation of a point (x, y)?

Back

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

Front

What is the definition of congruence in geometry?

Back

Congruence means that two figures have the same shape and size, and can be transformed into each other using rigid transformations.

Front

What is the difference between translation and reflection?

Back

Translation moves a figure without changing its orientation, while reflection flips it over a line.

Front

What does it mean for figures to be congruent after a transformation?

Back

It means that the figures remain identical in shape and size after the transformation.

Front

What is the effect of a reflection over the x-axis on the point (x, y)?

Back

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

Front

What is the effect of a translation of 5 units down on the point (x, y)?

Back

The new coordinates will be (x, y-5).
