Rotations transform shapes around a fixed point. Rotation requires centre of rotation, angle, and direction. Original shape becomes image, maintaining same size and shape. Rotations are called isometries when lengths remain constant
Reflection flips a shape across a line or plane without changing size or shape. Preimage is the original figure, image is the transformed version. Each point on the preimage moves same distance across reflection line
Rotation is a change in orientation without size change. There are six possible rotations: 90, 180, 270, 360 degrees. Clockwise rotations are negative, counterclockwise are positive. Direction doesn't matter for 180 and 360-degree rotations
