Find the cosine of the angle between planes
Web1 Answer. Sorted by: 2. You might define your normal vectors in such way that their dot product will be negative. It means the angle between planes will be obtuse. However, you probably needed an acute angle, so your teacher has applied the equality: cos ( θ) = − c o s ( π − θ) Share. Cite.
