Transformations

Front

What is a transformation in geometry?

Back

A transformation is a change in the position, size, or shape of a figure.

Front

What is translation?

Back

Translation is a transformation that moves a figure from one place to another without changing its shape or orientation.

Front

What is rotation?

Back

Rotation is a transformation that turns a figure around a fixed point called the center of rotation.

Front

What is reflection?

Back

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

Front

What does it mean to rotate a figure 90 degrees clockwise?

Back

To rotate a figure 90 degrees clockwise means to turn it to the right, so that the top of the figure moves to the right side.

Front

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

Back

Reflecting a figure over the x-axis means to flip it over the x-axis, changing the sign of the y-coordinates.

Front

What is the center of rotation?

Back

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

Front

Can a figure be translated and rotated at the same time?

Back

Yes, a figure can be translated and rotated at the same time, resulting in a new position and orientation.

Front

What is the difference between rotation and reflection?

Back

Rotation turns a figure around a point, while reflection flips it over a line.

Front

What is an example of a translation?

Back

Moving a triangle 5 units to the right and 3 units up is an example of a translation.
