Why do you think that the dihedral angle between two planes is never greater than 180 degrees?
|Manipulative 1 - Dihedral Angle Created with GeoGebra.||
A dihedral angle is the angle formed by two intersecting
The Intersecting Planes Postulate tells us that
planes form a line. Take a line in each plane that is
to the line of intersection. The two lines
must intersect. The dihedral angle of the planes is the angle between the two lines.
