angle between two points code example

Example 1: angle between two points

double angle = atan2(y2 - y1, x2 - x1) * 180 / PI;".

Example 2: how to find angle between two points

let angle = Math.atan2( y2 - y1, x2 - x1 ) * ( 180 / Math.PI )

Example 3: processing angle between two points

PVector v1 = new PVector(10, 20);
PVector v2 = new PVector(60, 80); 
float a = PVector.angleBetween(v1, v2);
println(degrees(a));  // Prints "10.304827"

Example 4: angle between two points

double angle = atan2(y2 - y1, x2 - x1) * 180 / PI;".
