I need to find the x,y coordinates of the points that neighbor a center point that has been rotated around yet another point. An illustration is best:

Given: point of origin, angle, p1, p2

Needed: p1 a, b, c etc, p2 a, b, c, etc

2. Relevant equations

for p1/p2 I just do:

ax = cosine(angle)

ay = sine(angle)

new x = ax * distance from origin + origin x

new y = ay * distance from origin + origin y

3. The attempt at a solution

I thought I just add/subtract an amount somehow, somewhere? Tried, couldn't find the right stuff.
