Pentagon, or pentahedron if it's a 3-D figure rather than a plane figure.
None. Since the number of sides is odd, there can be no parallel sides.
None.
None. (As there are an odd number of sides, each side is opposite a vertex and there are no parallel sides.)
It can have none, one or two pairs.
None!!!! A 7-sided polygon is named 'HEPTAGON'., However, An 8-sided polygon is named 'OCTAGON'.
Not all four-sided shapes have one pair of parallel sides. For example, a rectangle and a trapezoid can have one pair of parallel sides, but a general quadrilateral does not necessarily have any parallel sides. Shapes like rhombuses and squares have two pairs of parallel sides, while irregular quadrilaterals may have none. Thus, the presence of parallel sides depends on the specific type of four-sided shape.
A four-sided figure with no equal sides is an irregular quadrilateral.
None normally in a regular 5 sided pentagon but it is possible to construct an irregular pentagon with a pair of parallel sides.
None. A triangle based pyramid is a 4-sided solid (a tetrahedron), and has no parallel sides.
If all the sides are different lengths, it can only be called a quadrilateral. In general, four sided two dimensional objects are called quadrilaterals. When all four sides are the same length it is a square if all four corners are right angles. Otherwise it is a rhombus. If the opposite sides are the same length, it is a rectangle if the four corners are right angles, otherwise it is a parallelogram. In all these cases, the opposite sides are parallel to each other. There is also the trapezoid, a quadrilateral with only one pair of parallel sides. If the opposite sides are the same length but not parallel. it is an isosceles trapezoid.
There are no parallel sides in a right angle triangle
You are a rhombus.
