Trihedron

Pro Tip 1/3

Geometry Term

Trihedron is commonly used in geometry and technical fields to describe a three-faced shape.

In my geometry class, we learned how to calculate the angles of a trihedron.

Not Polyhedron

A trihedron has only three surfaces, unlike a polyhedron which has many.

A cube is not a trihedron; it's a polyhedron because it has six faces.

3D Understanding

Understanding 'trihedron' requires visualization of three-dimensional space, as it's a 3D shape.

Visualize a corner of a box; it's a trihedron where the faces meet.
