What is a lateral edge oblique prism?
A segment known as a lateral edge joins each vertex of a base with its corresponding vertex on the other base. The remaining faces are parallelograms, and are known as lateral faces. If the lateral edges are perpendicular to the bases, the lateral faces are rectangles and the prism is a right prism. Otherwise, the prism is an oblique prism.
How do you know if a prism is regular or oblique?
If the lateral edges are perpendicular to the bases, the lateral faces are rectangles and the prism is a right prism. Otherwise, the prism is an oblique prism. prism is named by the shape of its base. If its base is regular (i.e. all sides congruent and all angles congruent), then it is called a regular prism.
Which cylinder has a congruent cross section perpendicular to the bases?
Let us consider the following right cylinder and then draw some general conclusions. In the cross section parallel to the bases, the cross section is a circle which is congruent to the bases. In the cross section perpendicular to the bases, the cross section is a rectangle.
What is the axis of a cylinder?
The segment joining the centers of the two bases is called the axis of the cylinder. If the axis is perpendicular to the bases, then the cylinder is a right cylinder. If the axis is not perpendicular to the bases, then the cylinder is an oblique cylinder.
