The information given would suggest that the polygon in question is an isosceles trapezoid and not a parallelogram
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
2 are.
A parallelogram has both pairs of opposite sides parallel. A trapezoid has only one pair of sides parallel.
No. The only conditions to quality as a parallelogram is that it is a quadrilateral, and that opposite sides are parallel.
The Opposite Sides Parallel and Congruent Theorem states that if a quadrilateral has a pair of opposite sides that are parallel and congruent, then the quadrilateral is a parallelogram.
The angles between the sides that are parallel are congruent.The angles between the sides that are parallel are congruent.The angles between the sides that are parallel are congruent.The angles between the sides that are parallel are congruent.
A square's opposite sides are parallel and all the sides are congruent.
All 4 sides are congruent and opposite sides are parallel to each other.
A quadrilateral with congruent pairs of adjacent sides and no parallel sides is a kite.
No. It is the opposite sides of a regular octagon that are parallel and congruent.
