Calculating Reflection angle in a 2D plane.

AI Thread Summary
To calculate the reflection angle of two points in a 2D plane at different distances from a reflection surface, one must first determine the normal line at the point of reflection. The angles of incidence and reflection are equal, which can be used to derive the reflection angles for each point. Additional information about the coordinates of the points and the orientation of the reflection surface is necessary for accurate calculations. Clarifying the specific coordinates and distances involved will help in providing a more precise solution. Understanding these geometric principles is crucial for solving the reflection angle problem effectively.

Im trying to calculate the refelction angle of 2 points in a 2d plane, but not the same distance away from the reflection surface, and I'm drawing a blank.

Any help would be hugely appreciated.

:confused:

Can you provide some more description of your problem?
 
If I know x and y, how can i calculate x1 and x2 or 0?
