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 in a specific direction.

Front

What does a 180-degree clockwise rotation look like?

Back

A 180-degree clockwise rotation flips the figure upside down, effectively reversing its orientation.

Front

What is reflection in geometry?

Back

Reflection is a transformation that flips a figure over a line, creating a mirror image of the original figure.

Front

What is the line of reflection?

Back

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

Front

What is the difference between clockwise and counter-clockwise rotation?

Back

Clockwise rotation moves in the direction of the hands of a clock, while counter-clockwise rotation moves in the opposite direction.

Front

What is a translation in geometry?

Back

A translation is a transformation that moves a figure from one location to another without changing its shape, size, or orientation.

Front

What is the effect of reflecting a figure across the x-axis?

Back

Reflecting a figure across the x-axis flips it vertically, changing the sign of the y-coordinates of its points.

Front

What is the effect of reflecting a figure across the y-axis?

Back

Reflecting a figure across the y-axis flips it horizontally, changing the sign of the x-coordinates of its points.

Front

What is a sequence of transformations?

Back

A sequence of transformations is a series of geometric transformations applied one after the other to a figure.

Front

How do you perform a 90-degree clockwise rotation?

Back

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