Translation, Reflection, Rotation

Front

What is rotation in geometry?

Back

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 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 translation in geometry?

Back

Translation is a transformation that slides a figure from one position to another without changing its shape, size, or orientation.

Front

What is the center of rotation?

Back

The center of rotation is the fixed point around which a figure rotates during a rotation transformation.

Front

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

Back

Reflecting a figure over the x-axis means that each point of the figure is flipped to the opposite side of the x-axis, maintaining the same distance from the axis.

Front

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

Back

Reflecting a figure over the y-axis means that each point of the figure is flipped to the opposite side of the y-axis, maintaining the same distance from the axis.

Front

How do you identify a rotation transformation?

Back

A rotation transformation can be identified by the presence of a fixed point (center of rotation) and an angle that indicates how far the figure has been turned.

Front

What is the difference between rotation and reflection?

Back

Rotation turns a figure around a point, while reflection flips a figure over a line, creating a mirror image.

Front

What is an example of a translation?

Back

An example of a translation is moving a triangle 3 units to the right and 2 units up without changing its shape or orientation.

Front

What is the effect of a 90-degree rotation clockwise?

Back

A 90-degree rotation clockwise turns the figure to the right, changing the position of its points according to the rotation.
