Is a quadrilateral that is not a parallelogram a trapezoid?
No. A trapezoid must have one pair of parallel sides, and a parallelogram must have two pair.But a quadrilateral in general doesn't necessarily have any parallel sides.
Why is a trapezoid a quadrilateral but not a parallelogram?
Because a quadrilateral is any four-sided shape, whereas a parallelogram must have opposite sides and equal angels. A trapezoid only has two sides and equal angles.In other words, a parallelogram has 2 pairs of parallel sides but a trapezoid only has one pair (top and bottom).
What attribute makes a parrallelogram a special trapezoid?
A trapezoid is a quadrilateral which must have one pair of parallel sides. If the other pair of sides is also parallel then it is a parallelogram.
How is a parallelogram different than a trapezoid?
A trapezoid only has one pair of parallel sides, while all parallelograms must have two.
What are the rules of a trapezoid?
A trapezium must have one pair of parallel sides and the other sides must not be parallel - since in that case it becomes a parallelogram.
Is a parallelograms a trapezoids?
No. The formal definitions of parallelogram and trapezoid specifically exclude each other.A parallelogram is a quadrilateral with two pairs of parallel sides.A trapezoid is a quadrilateral with exactly one pair of parallel sides.
If a quadrilateral contains three congruent sides the quadrilateral must be a parallelogram true or false?
False. Could be a trapezoid.
Does a trapezoid's opposite sides parallel?
One pair must be. If the other pair is also parallel it becomes a parallelogram.
Are all quadrilaterals either trapezoids or parallelograms?
No. A trapezoid must have one pair of parallel sides, and a parallelogram must have two pair.But a quadrilateral in general doesn't necessarily have any parallel sides.
Parallelogram of only two of sides are parallel?
no, both 2 sides must be parallel because if only 1 side of it is parallel and the other pair is not it is called a trapezoid.
How can trapezoid be a parallelogram?
A trapezoid has only one pair of parallel lines so it cannot be a parallelogram which must have two pairs of parallel lines.
What trapezoid must have a pair of parallel sides and a pair of congruent sides?
An isosceles trapezoid must have a pair of parallel sides and a pair of congruent sides
