How does a reflection transformation work?

Back

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

What is the effect of translating a figure up by 5 units?

Back

Translating a figure up by 5 units moves every point of the figure 5 units higher on the y-axis.

What does it mean to rotate a figure 90 degrees counterclockwise?

Back

Rotating a figure 90 degrees counterclockwise means turning the figure around a point (usually the origin) by a quarter turn in the opposite direction of the clock hands.

What is the result of reflecting a figure over the x-axis?

Back

Reflecting a figure over the x-axis changes the sign of the y-coordinates of all points in the figure.

What is the sequence of transformations for Triangle ABC to Triangle A''B''C'' if it involves a rotation and reflection?

Back

The sequence involves a rotation of 90 degrees followed by a reflection over the x-axis.

How do you describe a translation of a figure?

Back

A translation of a figure is described by the direction and distance each point of the figure moves.

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.
