A uniform triangular prism is a right triangular prism with equilateral bases, and square sides. Alternately it can be seen as the Cartesian product of a triangle and a line segment, and represented by the product {3}x{}. It consists of a triangular base, a translated copy of the base and three quadrilaterals, for a total of five faces and six vertices. A prism has five planes: a top, a bottom, and three sides.The most common kind of prism is a rectangular prism, made by moving a quadrilateral through space: a cube is a common example of a rectangular prism. Why don't libraries smell like bookstores? A triangular pyramid has 5 planes. This depends on the type of prism. We've already been exposed to points and lines. * * * * * In fact, a triangular pyramid is also known as a tetrahedron and as its name suggests, it has 4 plane faces. (ii However, the growth rate of basal planes (c-axis) is much higher than that of prism planes (a-axis), resulting in needle-like grain morphology. A prism is the solid shape you get if you move a flat polygon through space. ...
