This is an interactive resource containing two activities about estimating and measuring angles. In the angle estimation activity, users can select acute, obtuse or reflex angles, or any angle between zero and 360 degrees. In the angle drag activity, one arm of the angle can be dragged to rotate around the vertex, creating angles of different sizes. Both activities have the options to show or hide the size of the angle and to overlay the angle with a virtual protractor.
