Angle
This example simply demonstrates the concept of fractions. Key mathematical concepts include the basic properties of fractions. Construction highlights the use of Circle, Rotate, Segment, and Angle commands in GeoGebra. Suitable for high-grade elementary or junior high school students to learn the basic concepts and operations of fractions.
