Yes, the opposite sides of a parallelogram are congruent.
A parallelogram is a quadrelateral with opposite sides parallel and congruent.
A parallelogram cannot have only two congruent sides, nor only two congruent angles.
Yes. That would make all sides congruent; in this case, your parallelogram would be a rhombus.
Not necessarily.
Yes.A parallelogram with all congruent sides is called a rhombus. A square is technically a parallelogram with all congruent sides as well.
No. If you made a parallelogram with congruent sides it wouldn't necessarily have congruent angles. A square has to have congruent angles as well as congruent sides.
They are sometime congruent because a square is a parallelogram and its sides are congruent and a rectangle is one and its sides aren't congruent.
Yes, the opposite sides of a parallelogram are congruent.
A parallelogram has two pairs of congruent sides.
A parallelogram with congruent sides is a rhombus.
A parallelogram with four congruent sides may be either a square or a rhombus.
A parallelogram is a quadrelateral with opposite sides parallel and congruent.
If two opposite sides are congruent in length and direction then they are parallel sides. THat would mean the other two sides are congruent making 4 parallel sides or a parallelogram
Yes - opposite sides of a parallelogram are congruent.
Parallelograms have sides. Opposite sides are congruent.
A parallelogram cannot have only two congruent sides, nor only two congruent angles.
