Hi,
Calculating the angles in 3D shapes can be a very frustrating and annoying thing. So, I was wondering, are there any mathematical terms, which describe a 3d angles?( "angles" between three lines- part of a sphere)
If there are such terms, suppose a triangular pyramid. Is the sum of those "angles" is a constant? just as the sum of angles in a triangle is 180 degrees.
