O par ell lines and no congruent lines
cones have no congruent sides cause they dont have sides
A regular pentagon does not have any parallel sides. In contrast, a pentagonal prism has two parallel and congruent bases.
Parallelograms have 4 sides, it is a quadrilateral with the opposite sides parallel, and the opposite angles are congruent.4
A parallelogram has two sets of equal and parallel sides. They may be described as "congruent" because they are of equal length but they are usually described as in the first sentence of this answer.
There are many such shapes. Any polygon with an even number of sides can have opposite sides that meet the above requirements.
A cone does not have any parallel lines
It has 2 congruent sides
how many congruent sides does a scalene triangle
A parallelogram. Opposite sides are parallel and congruent.parallelogram is a quadrilateral with two sets of parallel sides. The opposite sides of a parallelogram are of equal length, and the opposite angles of a parallelogram are congruent. The three-dimensional counterpart of a parallelogram is a parallelepiped.Parallelogram - A quadrilateral whose opposite sides are parallel
A trapezoid normally has no congruent sides
It all depends on what kind of polygon it is. It may have no congruent sides or all congruent sides.
