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.

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.

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.

What is the center of rotation?

Back

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

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.

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.

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.

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.

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.

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.
