What is the ways to prove that a quadrilateral is a parallelogram?
If it is a parallelogram, then it has two sets of parallelogram sides. Parallelograms' opposite angles are congruent A parallelogram's bisectors are congruent. * * * * * A parallelogram's bisectors are NOT congruent.
Is a rectangle always a square never a square or sometimes a square?
sometime actually -A rectangle is a parallelogram with 4 right angles. -A square is a parallelogram with 4 right angles and 4 congruent sides. Congruent sides are the same length.
Are both pairs of opposite angles of a parallelogram are always congruent?
Yes

Are consecutive angles in a parallelogram always congruent?
Not unless the parallelogram is a rectangle. In every parallelogram, consecutive angles are supplementary.
Is parallelogram can have no congruent angles?
No. In a parallelogram, opposite angles are congruent.
Does a parallelogram have angles that are congruent?
Yes, opposite angles of a parallelogram are congruent.
Is a square always sometimes or never a rectangle?
It is never a rectangle but they are both 4 sided quadrilaterals
Is a rectangle always a square never a square or sometimes a square?
sometime actually -A rectangle is a parallelogram with 4 right angles. -A square is a parallelogram with 4 right angles and 4 congruent sides. Congruent sides are the same length.
What angles of a parallelogram are congruent?
the opposite angles are congruent
Opposite angles in a parallelogram are always congruent?
yes indeed
Are both pairs of opposite angles of a parallelogram are always congruent?
Yes
Can congruent angles determine if there is a parallelogram?
If both pairs of opposite angles of a quadrilateral are congruent, then it is a parallelogram.
Is a parallelogram with congruent sides a square?
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.
