Prisms

Prisms are one of the three categories of Polyhedrons. Prisms are 3D shapes with parallel and congruent* end faces, with the shape of the pair of congruent faces giving each prism its name.

*Congruent figures have exactly the same shape and size.

    Dear Miss Tomat,
    It is not a prism because the side (face/s) are not rectangler.

    Dear Miss Tomat,

    These are our answers:

    1. Yes it is because there is no vertices and if it was to be a pyramid it would have to have a vertex at the top.
    2. In mathematics a conic section is a curve obtained as the intersection of a cone (more precisely, a right circular conical surface) with a plane.
    3. A Rhombic prism is like a parrellelagram just 3D.

    Dear Miss Tomat,

    A cylinder is not a prism because it has curved lines.

    Conic means a figure formed by the intersection or a plane and circular cone, depending on the angle of the plane with the respect of the cone. A conic section may be a circle.

    Did you know that the rhombic prism is like a cube on a tilt, just like a rhombus that is a square on a tilt.
