js can you find the angle of a line in canvas code example
Example: javascript angle equation of a line
// point 1 (x1, y1) or origine of vertex
// point 2 (x2, y2)
var dx = x2 - x1
var dy = y2 - y1
var ang = Math.atan2(dy, dx) * 180 / Math.PI;// point 1 (x1, y1) or origine of vertex
// point 2 (x2, y2)
var dx = x2 - x1
var dy = y2 - y1
var ang = Math.atan2(dy, dx) * 180 / Math.PI;
