Define translation in geometry.

Back

Translation is a type of transformation that slides a figure in a straight line from one position to another without changing its size, shape, or orientation.

What is a rotation in geometry?

Back

A rotation is a transformation that turns a figure around a fixed point, known as the center of rotation, by a specified angle.

What is reflection in geometry?

Back

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

What does it mean for a shape to have rotational symmetry?

Back

A shape has rotational symmetry if it can be rotated around a central point and still look the same at certain angles.

How do you determine the angle of rotation for a shape?

Back

The angle of rotation is determined by how far the shape is turned around the center of rotation, measured in degrees.
