The lateral faces of a prism are either squares, rectangles or parallelograms. If the prism is oblique then the faces must be parallelograms and not rectangles or squares.
The lateral faces will be parallelograms, and the opposite faces will be congruent. In a right prism, the lateral faces will be rectangles.
In a right prism, the lateral sides are perpendicular to the bases and so all of them are rectangular.In an oblique prism, the lateral sides are not perpendicular to the bases so that some of them (at least) are non-rectangular parallelograms.In a right prism, the lateral sides are perpendicular to the bases and so all of them are rectangular.In an oblique prism, the lateral sides are not perpendicular to the bases so that some of them (at least) are non-rectangular parallelograms.In a right prism, the lateral sides are perpendicular to the bases and so all of them are rectangular.In an oblique prism, the lateral sides are not perpendicular to the bases so that some of them (at least) are non-rectangular parallelograms.In a right prism, the lateral sides are perpendicular to the bases and so all of them are rectangular.In an oblique prism, the lateral sides are not perpendicular to the bases so that some of them (at least) are non-rectangular parallelograms.
