In what quadrilaterals are consecutive and opposite angles always congruent?
Square and Rectangle
What are the 5 properties of parallelograms?
If one angle is right, then all angles are right. The diagonals of a parallelogram bisect each other. Opposite angles are congruent. Opposite sides are congruent. Consecutive angles are supplementary.
Which parallelograms have congruent diagonals?
Only rectangles (squares included) have congruent diagonals, because all their angles are congruent (90 degrees). If you have angles larger or smaller than 90 degrees it makes the diagonals different lengths.
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.
How many sides are there in parallelogram?
Parallelograms have 4 sides, it is a quadrilateral with the opposite sides parallel, and the opposite angles are congruent.4
How many congruent angles does a parallelograms?
Two pairs.
In what quadrilaterals are consecutive and opposite angles always congruent?
Square and Rectangle
Do all parallelograms have diagonals which bisect?
Yes; all parallelograms have diagonals that bisect each other. Other properties of parallelograms are: * The opposite sides are congruent. * The opposite sides are parallel. * The opposite angles are congruent.
Are angles and sides of a parallelogram congruent?
In all parallelograms, opposite angles and opposite sides are congruent. If all four sides are congruent, it's a rhombus. If all four angles are congruent, it's a rectangle. If all four sides and all four angles are congruent, it's a square.
What are two parallegrams that are congruent?
They are simply two congruent parallelograms.
Are opposite angles of a parallelogram congruent for all parallelograms?
angles diagnal from each other in a parallelogram are congruent for shape be parallelogram, all sides must be parallel
What is always true about parallelograms?
Both pairs of opposite sides are parallel + congruent, and both pairs of opposite angles are also congruent.
Does a quadrilateral have congruent angles?
A quadrilateral is a plane figure with four straight sides and does not necessarily have any congruent angles. Some quadrilaterals such as, squares, rectangles, rhombuses, and parallelograms do have congruent angles.
What are the 5 properties of parallelograms?

What is are the relationships between parallelograms?
A parallelogram has two sets of parallel sides. Opposite sides of a parallelogram are congruent. This means that opposite angles are congruent as well. All parallelograms must fit this description or else it's not a parallelogram.
