Angle, Bisector of Dihedral
Illustration of a dihedral angle bisected by a plane. "Every point in a plane which bisects a dihedral angle is equidistant from the faces of the angle."... |

Angle, Convex Polyhedral
Illustration of a convex polyhedral angle. "The sum of the face angles of any convex polyhedral angle is less than four right angles."... |

Angle, Polyhedral
Illustration of polyhedral angle. "The opening of three or more planes which meet at a common point is called a polyhedral angle."... |
|
Angle, Trihedral
Trihedral angle. "The sum of any two face angles of a trihedral angle is greater than the third face angle."... |
