Angles Inside Shapes - Estimate then Measure
Estimate, then accurately measure, an angle inside a shape.
Part of a series of angle estimating and measuring activities.
Choose whether to play with triangles, quadrilaterals or polygons. Measure angles inside the shapes by first estimating them, then use the interactive protractor to measure the angle accurately. (You can use the sliders to enlarge/reduce the protractor size, and fade it.)
You will be shown and told how accurate your estimation and measure are. The closer you are, the better the feedback! Can you get it right?
