A right triangular prism, explained.
A right triangular prism has two congruent parallel triangular bases and three rectangular lateral faces. The prism length is perpendicular to the triangular base planes. Its base triangle need not be equilateral or right-angled.
Understand the properties ↗LOOK A LITTLE CLOSER
More than a formula.
It has five faces, nine edges and six vertices.
A triangle’s altitude and the prism’s length are distinct. Oblique prisms require a different treatment of lateral surface area.
