What is a rotation in geometry?

Back

A rotation is a transformation that turns a figure around a fixed point, called the center of rotation, by a certain angle.

What does it mean to reflect a figure over the x-axis?

Back

Reflecting a figure over the x-axis means flipping the figure across the x-axis, changing the sign of the y-coordinates of the points.

What is the effect of translating a figure?

Back

Translating a figure means moving it from one location to another without changing its shape, size, or orientation.

How do you perform a 90-degree rotation counterclockwise about the origin?

Back

To perform a 90-degree rotation counterclockwise about the origin, switch the coordinates of each point (x, y) to (-y, x).

What is the order of transformations, and why is it important?

Back

The order of transformations is crucial because changing the sequence can lead to different final positions and orientations of the figure.

What is the transformation from Triangle ABC to Triangle A''B''C'' if it involves a rotation and reflection?

Back

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

What does it mean to translate a figure right by 6 units?

Back

Translating a figure right by 6 units means adding 6 to the x-coordinates of all points in the figure.

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.
