Front

What is a rigid transformation?

Back

A transformation that preserves the shape and size of a figure, including translations, rotations, and reflections.

Front

What does it mean to translate a figure?

Back

To slide a figure from one position to another without changing its shape, size, or orientation.

Front

What is a reflection in geometry?

Back

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

Front

What is a rotation?

Back

A transformation that turns a figure around a fixed point at a certain angle.

Front

What does a translation of 5 units down mean?

Back

It means moving every point of the figure 5 units downward on the coordinate plane.

Front

How do you describe a reflection over the x-axis?

Back

Each point of the figure is mirrored across the x-axis, changing the sign of the y-coordinate.

Front

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

Back

The figure turns 90 degrees in the clockwise direction around a fixed point.

Front

If a triangle is translated left 2 and up 9, what happens to its coordinates?

Back

Each point's x-coordinate decreases by 2 and the y-coordinate increases by 9.

Front

What is the effect of a dilation on a figure?

Back

A transformation that changes the size of a figure but not its shape.

Front

What does it mean to slide a figure?

Back

It refers to the process of translating the figure without altering its orientation or size.
