What is My Angle? App

Published on 10/17/2008

Activity Overview

This App allows students to practice estimating the size of angles in degree measure using real-world examples such as the angle between the hands of a clock, TV antennas, and more. The App draws an angle in a positive direction and students input an estimated degree measure (in 5-degree increments). If an estimate is incorrect, multiple-choice answers appear to help make the estimate.
