Use the slider below and investigate what different angles look like. Once you find an acute, right, and obtuse angle, draw your own.
Make sure your work is neat and remember to label your angles!
If you are having trouble finding a right angle, try carefully moving the slider to the exact point in which the angle turns from acute to obtuse. There is only one right angle, so keep looking!
Use the eTool below to explore the problem.
