HallsofIvy, I am still having some difficulty with this vector problem. I used your method to calculate the new coordinates of C' and using those coordinates to calculate the magnitude of the vector AC' it indeed does equal the magnitude of AC + CC'. The next part still doesn't seem to...

This is perfect and exactly what I was looking for, thank you very much. Just to clarify, I believe you intended to say, "Then each coordinate of C' has distance from A equal to (h+ H)/H...". That part is really the heart of the matter and I am still trying to understand that graphically. The...

I'm not sure if this the correct area but Ill go ahead anyways. I have three points (A, B, and C) in 3D space that form a triangle. All three points have the (x,y,z) coordinates defined. Using the dot product I have solved for the angle θ (or in other notation the angle ABC) of the...
