How can you used a triangle to prove quadrilateral is a parallelogram?
A quadrilateral, in general, is not a parallelogram. If it is a parallelogram then you will have some additional information about its sides and angles. If you do not have such information it is not possible to prove that it is a parallelogram. Draw a diagonal which will divide the quadrilateral into two triangles and use the additional information that you have to show that the triangles are congruent. This can then be used to show equality of sides or of angles: the latter can then be used to show that sides are parallel. Note that the choice of which diagonal may influence how (if at all) you proceed.
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 of the following is a valid reason why the quadrilateral shown below is a parallelogram?
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.
What are the proofs that a quadrilateral ia s parallelogram?
There are 5 ways to prove a Quadrilateral is a Parallelogram. -Prove both pairs of opposite sides congruent -Prove both pairs of opposite sides parallel -Prove one pair of opposite sides both congruent and parallel -Prove both pairs of opposite angles are congruent -Prove that the diagonals bisect each other

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.
What is a quadrilateral parallelogram?
A quadrilateral is a polygon with four sides. A parallelogram is a quadrilateral in which the opposite sides are parallel.
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.
If one diagonal of a quadrilateral bisects the other when is the quadrilateral a parallelogram?
In this case, the quadrilateral is sometimes a parallelogram.
If opposite angles of a quadrilateral are supplementary is the quadrilateral a parallelogram?
No. A quadrilateral is a parallelogram when consecutiveangles are supplementary.
Is a parallelogram any other kind of quadrilateral?
No, a parallelogram is not another kind of quadrilateral.
