How do you calculate angle between 2 planes in 3 D? Watch this video to find out. Here, we learn how to calculate angle between 2 planes. We learn how to check if 2 planes are parallel or perpendicular. We also learn how to find the angle between a line and a plane. The intersection of 2 planes is also touched upon. This is a part of grade 12 mathematics. It is also useful for the NATA ELIGIBILITY test for architecture.
