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.

Explain reflection in geometry.

Back

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

What is dilation in geometry?

Back

Dilation is a transformation that changes the size of a figure but not its shape, using a scale factor.

How do you perform a translation of a point (x, y) by (a, b)?

Back

To translate the point (x, y) by (a, b), add a to x and b to y, resulting in the new point (x+a, y+b).

What is the effect of a 90-degree rotation counter-clockwise around the origin on a point (x, y)?

Back

The new coordinates after a 90-degree counter-clockwise rotation are (-y, x).

How does a reflection over the x-axis affect the coordinates of a point (x, y)?

Back

A reflection over the x-axis changes the coordinates to (x, -y).

What is the result of a dilation with a scale factor of 2 on a point (x, y)?

Back

The new coordinates after dilation with a scale factor of 2 are (2x, 2y).
