Правильна трикутна призма – призма, which is based on two right triangles, and all side faces are strictly perpendicular to these bases.
Wedge – це багатогранник, the two faces of which are equal triangles, lying in parallel planes, and other facets (side faces) – паралелограма, which have common sides with these triangles.
Correct triangular prism – це трикутна призма у якої основи правильні трикутники (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! Історично поняття “призма” виникло з латині і означало – щось відпиляне. 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.
