Correct triangular prism – prism, which is based on two right triangles, and all side faces are strictly perpendicular to these bases.
Wedge – it is a polyhedron, the two faces of which are equal triangles, lying in parallel planes, and other facets (side faces) – parallelogram, which have common sides with these triangles.
Correct triangular prism – it is a triangular prism based on right triangles (all sides of which are equal, the angles between the sides of the base are 60 C), and the side faces are rectangles.
An interesting fact! Historical concept “prism” originated from Latin and meant – something sawn off. The animation demonstrates how two parallel planes cutting off the excess form the two bases of the prism. From one blank you can get the right prism, and an inclined prism.
The side faces of the prism are rectangles.
