ANSWER: A parallelogram (It can also be called a trapezoid) ... but a trapezoid is not a parallelogram!
A trapezoid is sometimes a parallelogram. If the trapezoid has two pairs of parallel sides, it will also be a parallelogram. However, if the trapezoid does not have two pairs of parallel sides, it will not be a parallelogram.
Square = parallelogram and a square trapezoid = trapezoid Parallelogram = Parallelogram
A trapezoid can also be a parallelogram if its non-parallel sides are of equal length.
First of all, a trapezoid is not always a parallelogram. Did you mean the reverse: "Why is a parallelogram also a trapezoid"? If so, this depends upon your definition of a trapezoid and parallelogram. Some people define a trapezoid as a quadrilateral with exactly one pair of parallel sides, and a parallelogram as a quadrilateral with exactly two pairs of parallel sides. According to these definitions, a trapezoid can *NEVER* be a parallelogram, so your question is meaningless. However, others might define a trapezoid as a quadrilateral with one *or two* pairs of parallel sides. If you use this definition, then all parallelograms are also trapezoids, much in the same manner that all squares are also rectangles.
No, a trapezoid is not a parallelogram.
no
Parallelogram
A trapezoid is not a type of parallelogram. A parallelogram is a type of trapezoid.
is a trapezoid a parallelogram
A trapezoid is not a parallelogram because they both have different properties but they are both 4 sided quadrilaterals
parallelogram?
No, a parallelogram is not always a trapezoid, but they are both four-sided quadrilaterals. A parallelogram has two pairs of parallel sides, and a trapezoid has only one pair of parallel sides.
No, a trapezoid is not a parallelogram.
There are absolutely no trapezoids that are also parallelograms.
A trapezoid.
A trapezoid is different to parallelogram! Because trapezoid has one pair of parallel line and parallelogram has two pairs! PS. it obvious that these shapes is different you fool!
