startAngleNumber
The start angle of the arc in decimal degrees. Measured in clockwise direction with 0 pointing "right". Negative values or values greater than 360 will be normalized.
Example
<script>
var geom = kendo.geometry;
var arc = new geom.Arc([70, 70], {
radiusX: 35,
radiusY: 25,
startAngle: 120,
endAngle: 300
});
console.log(arc.startAngle); // 120
</script>
