Translation, Reflection, Rotation

Front

What is Translation in geometry?

Back

Translation is a transformation that moves every point of a figure the same distance in a specified direction.

Front

What is Reflection in geometry?

Back

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

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.

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.

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.

Front

What is the result of translating a figure 3 units to the right?

Back

The figure moves 3 units in the positive x-direction, changing the x-coordinates of all points by adding 3.

Front

What is the result of rotating a figure 90 degrees clockwise?

Back

Each point of the figure moves to a new position that is 90 degrees clockwise around the center of rotation.

Front

How can you identify a reflection transformation?

Back

A reflection transformation can be identified by the symmetry of the figure across a line.

Front

What is the difference between translation and reflection?

Back

Translation moves a figure without changing its orientation, while reflection flips it over a line, changing its orientation.

Front

What is an example of a real-life reflection?

Back

A real-life example of reflection is seeing your image in a mirror.
