Are sides of a parallelogram always sometimes or never congruent?
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.
If one pair of opposite sides of a quadrilateral are congruent then the quadrilateral is a parallelogram?
No, you need both pairs of opposite sides to be congruent (i.e. the same size) to be a parallelogram.
What quadrilaterals opposite sides are congruent?
A parallelogram (and all its special cases) has two pairs of opposite sides that are congruent. An isosceles trapezium has one pair of congruent opposite sides. Selected irregular quadrilaterals can have a pair.
What are the similarities between a parallelogram and a trapezoid?
A parallelogram has two pairs of sides that are parallel when a trapezoid only has one. A parallelogram's opposite sides are congruent and opposite angles are congruent. A trapezoid has no opposite congruent sides or angles, unless it's an isosceles trapezoid, which base angles are congruent. They both have four sides and four interior angles that add up to 360 degrees.
What is a quadrilateral that is not a parallelogram?
a kite (two pairs of adjacent congruent sides) or a trapezoid (one pair of parallel sides).
Are sides of a parallelogram always sometimes or never congruent?
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.
Is Opposite sides congruent one of the properties of a parallelogram?
A parallelogram is a quadrelateral with opposite sides parallel and congruent.
If one pair of adjacent sides of a parallelogram is congruent then the parallelogram must be a?
Rhombus.
What is a quadrilateral with four congruent sides?
A square. Parallelogram * * * * * No. It is a rhombus and a square is a special case of a rhombus. A parallelogram does not have four congruent sides, but two pairs of sides that are congruent to one another.
If one pair of opposite sides of a quadrilateral is congruent then the quadrilateral is a parallelogram?
No. The congruent sides need not be parallel.
If one pair of opposite sides of a quadrilateral are congruent then the quadrilateral is a parallelogram?
No, you need both pairs of opposite sides to be congruent (i.e. the same size) to be a parallelogram.
If one pair of opposite sides of a quadrilateral are congruent then it is a parallelogram?
No, it is not.
What quadrilaterals opposite sides are congruent?
A parallelogram (and all its special cases) has two pairs of opposite sides that are congruent. An isosceles trapezium has one pair of congruent opposite sides. Selected irregular quadrilaterals can have a pair.
What quadrilaterals has exactly one pair of opposite sides that are congruent?
Parallelogram, Rectangle, and Isosceles Trapezoid, opposite sides are congruent.
How many equal sides does a Parollogram?
A parallelogram has two pairs of congruent sides (sides that have the same measure); for example, the top and bottom sides are congruent with one another, and the left and right sides are congruent with one another.
What are the similarities between a parallelogram and a trapezoid?
A parallelogram has two pairs of sides that are parallel when a trapezoid only has one. A parallelogram's opposite sides are congruent and opposite angles are congruent. A trapezoid has no opposite congruent sides or angles, unless it's an isosceles trapezoid, which base angles are congruent. They both have four sides and four interior angles that add up to 360 degrees.
If one pair of opposite sides of a quadrilateral is parallel and then the quadrilateral is a parallelogram?
Then, the opposite sides are congruent.
