Help me do what I need to do

I am a programmer and my math skills are weak.

I want to draw an arrow. I know the start and end points of the arrow.

I need to draw the arrow head which will be made up of three points
Point 1 is the end point which I already know

Point 2 and 3 would be a 45 degree angles a certain distance away from the end point. What is the magical math formula to calculate what points 2 and 3 are?
