# Angle

From JSXGraph Wiki

### The underlying JavaScript code

```
var brd = JXG.JSXGraph.initBoard('jxgbox', {boundingbox:[-2,2,2,-2]});
var A = brd.create('point', [-1,-1]),
B = brd.create('point', [1,-1]),
C = brd.create('point', [0,1]),
alpha = brd.create('angle', [B,A,C], {type:'sector', orthoType:'square', orthoSensitivity:2, radius:0.5}),
beta = brd.create('angle', [C,B,A], {type:'sector', orthoType:'sectordot', orthoSensitivity:2, radius:0.2});
```
