What is a reflection in geometry?

Back

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

Front

How do you reflect a point across the X-axis?

Back

To reflect a point (x, y) across the X-axis, the new point will be (x, -y).

Front

How do you reflect a point across the Y-axis?

Back

To reflect a point (x, y) across the Y-axis, the new point will be (-x, y).

Front

What is a rotation in geometry?

Back

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

Front

What is the result of rotating a point 90 degrees clockwise around the origin?

Back

The new coordinates of a point (x, y) after a 90-degree clockwise rotation will be (y, -x).

Front

What is the result of rotating a point 90 degrees counterclockwise around the origin?

Back

The new coordinates of a point (x, y) after a 90-degree counterclockwise rotation will be (-y, x).

Front

What is a translation in geometry?

Back

A translation is a transformation that moves every point of a figure the same distance in the same direction.

Front

How do you perform a translation of a point (x, y) by (x+5, y+2)?

Back

The new point will be (x+5, y+2).

Front

What is the difference between reflection and rotation?

Back

Reflection creates a mirror image over a line, while rotation turns a figure around a point.

Front

What is the coordinate of point W after reflecting it across the X-axis if W is at (4, 1)?

Back

Point W' will be (4, -1).
