MinorSector

Element

A minor sector is a sector of a circle having measure at most 180 degrees (pi radians). It is defined by a center, one point that defines the radius, and a third point that defines the angle of the sector.

Usage (signatures)

board.create('minorsector', [center, p1, p2]);

A minor sector is a sector of a circle around center spanning an angle of less than or equal to 180 degrees (π radians) and starts at p1. The radius is determined by p1, the angle by p2.

Parameters

Name	Type	Description
`center`	PointLike
`p1`	PointLike
`p2`	PointLike

Examples

// Create sector out of three free points
var center = board.create('point', [2.0, 2.0]);
var p1 = board.create('point', [1.0, 0.5]);
var p2 = board.create('point', [3.5, 1.0]);

var a = board.create('minorsector', [center, p1, p2]);

var A = board.create('point', [3, -2]),
    B = board.create('point', [-2, -2]),
    C = board.create('point', [0, 4]);

var angle = board.create('minorsector', [B, A, C], {
        strokeWidth: 0,
        arc: {
        	 visible: true,
        	 strokeWidth: 3,
          lastArrow: {size: 4},
          firstArrow: {size: 4}
        }
      });
// angle.arc.setAttribute({firstArrow: false});
angle.arc.setAttribute({lastArrow: false});
