Class Detail
Semicircle(p1,p2)
- Parameters:
- {JXG.Point_JXG.Point} p1,p2
- The result will be a composition of an arc drawn clockwise from p1 and p2 and the midpoint of p1 and p2.
- Throws:
- {Error}
- If the element cannot be constructed with the given parent objects an exception is thrown.
- Examples:
// Create an arc out of three free points var p1 = board.create('point', [4.5, 2.0]); var p2 = board.create('point', [1.0, 0.5]); var a = board.create('semicircle', [p1, p2]);
