Question

Julian describes an angle in the triangle using these statements. GH is the adjacent side. HK is the opposite side. GK is the hypotenuse.Which angle(s) is Julian describing? *

Answer 1

 my c++ application I have a 3d plane, with a point above it. The plane is rotated, and the point is at 0,0,0.

In the image below, the plane is represented by the triangle side B - C. (S3)

A is the point that is at zero. B is the mid-point of the plane.

What I need to calculate is the distance from Point A, to where it intersects the plane (Point C).

I know the angle of the plane, and the coordinates of point A and Point B.
