What is a rotation? A rotation is a type of transformation that takes each point in a figure and rotates it a certain number of degrees around a given point. For example, this animation …

Given a figure on the coordinate plane and the definition of a rotation about the origin, manually draw the image of that rotation.

To see the angle of rotation, we draw lines from the center to the same point in the shape before and after the rotation. Counterclockwise rotations have positive angles, while clockwise …

Learn how to draw the image of a given shape under a given rotation about the origin by any multiple of 90°.

In geometry, rotations make things turn in a cycle around a definite center point. Notice that the distance of each rotated point from the center remains the same. Only the relative position …

Given a figure on the coordinate plane and a center of a rotation, find the angle for the rotation that maps one figure to the other.

In this topic you will learn about the most useful math concept for creating video game graphics: geometric transformations, specifically translations, rotations, reflections, and dilations.

Learn how to determine which rotation brings one given shape to another given shape.

When you are given the degree of rotation, you want to describe it in mathematical terms. For example, if there is a point A being rotated 60 degrees about another point P and the …

Is there any more efficient way to do a rotation? Drawing a right triangle to every single point sounds kind of inefficient, especially if the shape happens to have a lot of points, and that …
