The Conopial Arc is a special type of circular arc used to demonstrate geometric and geometric construction concepts. This example uses GeoGebra commands and objects, including Segment, Midpoint, Line, Circle, Intersect, etc., to construct and display the properties of the Conopial Arc. This example is suitable for middle school and high school students learning geometric and geometric construction concepts, particularly the properties of circular arcs and circles.
