Is it true that The diagonals of a quadrilateral must bisect each other and be perpendicular to guarantee that the quadrilateral is a parallelogram?
no
Is parallelogram and quadrilateral the same thing?
No. A parallelogram is a special kind of quadrilateral.
What shape is a parallelogram but not a quadrilateral?
A shape that is a parallelogram but not a quadrilateral doesn't exist.
How do you find a parallelogram in a quadrilateral?
It's not a matter of 'finding' it. Either the quadrilateral is a parallelogram,or else it is not one.If the opposite sides of the quadrilateral are parallel, then it's a parallelogram.
If a quadrilateral is a square then it is a parallelogram. A quadrilateral is a square if and only if it is a parallelogram.?
The second statement is false.
Which description does not guarantee that a quadrilateral is a square?
"It has four sides" is a description that does not guarantee that a quadrilateral is a square.
True or false the diagonals of a quadrilateral must bisect each other and be perpendicular to guarantee that the quadrilateral is a parallelogram?
False. Bisecting diagonals is sufficient to guarantee a parallelogram, but the diagonals will only be perpendicular if the sides of the parallelogram are equal.
Which of these conditions does not guarantee that a quadrilateral is a parallelogram?
None of the conditions on the list that accompanies the question guarantees that a quadrilateral is a parallelogram. But then, none of them prevents it either.
The diagonals of a quadrilateral must bisect each other and be perpendicular to guarantee that the quadrilateral is a parallelogram?
False
The diagonals of a quadrilateral must bisect each other and be perpendicular to guarantee that the quadrilateral is a parallelogram.?
false
Is it true that The diagonals of a quadrilateral must bisect each other and be perpendicular to guarantee that the quadrilateral is a parallelogram?
no
Conditions which guarantee that a quadrilateral is a parallelogram?
Theorem A: A quadrilateral is a parallelogram if its opposite sides are congruent. Theorem B: A quadrilateral is a parallelogram if a pair of opposite sides is parallel and congruent. Theorem C: A quadrilateral is a parallelogram if its diagonals bisect each other. Theorem D: A quadrilateral is a parallelogram if both pairs of opposite angles are congruent.
A quadrilateral with 4 congruent sides is?
Either a square or a parallelogram fit this description.
Why is a parallelogram always a quadrilateral but a quadrilateral is only sometimes a parallelogram?
A parallelogram must have 4 sides and so it must be a quadrilateral. However, the sides of a quadrilateral need not be parallel so a quadrilateral need not be a parallelogram.
Which description does not guarantee that a quadrilateral is a rectangle?
A quadrilateral is not necessarily a rectangle. The only time this is not true is in the case of a square on a quadrilateral without four 90 degree angles.
What is a quadrilateral where opposite angles are congruent?
A parallelogram. A square or rectangle would also technically fit this description.
What is a quadrilateral that has 2 separate pairs of equal length but is not a parallelogram?
A kite would fit the given description
