What is a Rotation?
Transformations, isn't that geometry? The instructor illustrates how to rotate a shape around a fixed point on a graph, keeping the shape the same size.
Corbett Maths
Rotational Symmetry
Turn to the resource to discover rotational symmetry. Viewers of an informative video first learn the definition of rotational symmetry. They then see how to identify the order of rotational symmetry for a figure.
Socratica
Introduction to Angles Using Degrees
What's your angle? Individuals learn how angles are measured by watching a video in the Socratica Geometry series. The video explains acute, right, obtuse, and straight angles.

Virtual Nerd: What Is a Transformation?
To transform means to change. Transformations in math allow you to change or move a figure either by reflection, rotation, or translation. [4:18]
