Rotation. "Rotation" means turning around a center: The distance from the center to any point on the shape stays the same. Every point makes a circle around the center: Here a triangle is rotated around. the point marked with a "+" Try It Yourself. Here you can drag the pin and try different shapes:
Rotations are transformations that turn a shape around a fixed point. To rotate a shape we need: a centre of rotation. an angle of rotation (given in degrees) a direction of rotation – either clockwise or anti-clockwise. (Anti-clockwise direction is sometimes known as counterclockwise direction). E.g.
There are 4 types of transformations we need to know: • Translations. • Rotations. • Reflections. • Enlargements. Translations. A translation moves a shape. All points of the shape must be moved by the same amount. A translation can be up or down and left or right. Example: Describe the transformation that maps shape A onto shape B.
Jan 21, 2020 · A rotation is an isometric transformation that turns every point of a figure through a specified angle and direction about a fixed point. To describe a rotation, you need three things: Direction (clockwise CW or counterclockwise CCW) Angle in degrees. Center point of rotation (turn about what point?)
