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.
A parallelogram with 4 congruent sides is known as a rhombus.
it is a square
a paralleogram has four sides
A paralleogram having 4 congruent sides means it would be a rhombus or a square if it had right angles.
2 are.
Opposite angles in a parallelogram are congruent.
The information given would suggest that the polygon in question is an isosceles trapezoid and not a parallelogram
It has 2 congruent sides
how many congruent sides does a scalene triangle
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.
If it is a regular pentagon then it will have 5 congruent sides.
