a right triangle, a pentagon w/ a right angle, alot of shapes with right angles.
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.
For the perimeter, you just go round the shape, adding the lengths of each side as you go along. There may or may not be simple formulae of the area for a shape with unequal sides. If all you know is the [different] side lengths then only a triangle has a relatively simple formula for its area. If you also know that some of the sides are parallel, then you can find the area of a rectangle. Then, if you also know the perpendicular distance between the parallel sides, you can do a parallelogram. If, in addition you know which sides are parallel, a trapezium. And so on.
A polygon need not have ANY perpendicular or parallel lines. For example, consider an equilateral triangle. It can happen that two sides of a polygon, extended if necessary, meet at a point where they form a 90 degree angle. Those two lines are perpendicular. There may be pairs of lines such that, no matter how far you extend them in either direction, they will never meet. Such lines are parallel. A triangle cannot have parallel lines but it can have perpendicular lines. Any polygon of 4 or more sides can have sides that are perpendicular or parallel (or some of each).
Any polygon must have at least three sides. So a shape with only one pair of adjacent sides must be lenticular (shaped like a lens) else it is some very odd shape.

I think rectangles do not have perpendicular sides. there are some perpendicular sides in a rectangle stupid person
there is no sutch thing in the holl intier world or uneveres anlese some one made a shap up called one set of parellel sides
they for some shape

An octahedron is a closed 3-d shape with 8 polygonal faces. There are 257 topologically different convex octahedra. Some of these have no parallel sides whereas a right hexagonal prism has 3 quartet of parallel sides and one sextet.
A perpendicular shape is one where either one or more or even all of the angles are right angles. Some examples are rectangles and squares.
count the corners! Penta=5, five sides=5 angles, five angles equal 5 intersections. Some of these may be perpendicular, but not necessarily.
Some do, some don't
i how you doing ;;;;;;; may i please ask you a question he\she a shape that has two sides that are 4 centimeters and two sides that are 2 centimeters. comostas
