A trapezoid has one pair of parallel sides and a parallelogram has two pairs of parallel sides so can't really say it is.
why a trapezoid cant be called parallelogram
No, a trapezoid is not a parallelogram. A trapezoid is a quadrilateral with only one pair of parallel sides, whereas a parallelogram is a quadrilateral with both pairs of opposite sides parallel.
To understand why a trapezoid is not a parallelogram, let's break it down further:
1. Definition of a trapezoid: A trapezoid is a quadrilateral with one pair of parallel sides. The other two sides are not necessarily parallel to each other.
2. Definition of a parallelogram: A parallelogram is a quadrilateral with both pairs of opposite sides parallel. This means that the top and bottom sides are parallel and the left and right sides are also parallel.
Based on these definitions, we can see that a trapezoid does not meet the criteria for a parallelogram. In a trapezoid, only one pair of opposite sides is parallel, whereas in a parallelogram, both pairs of opposite sides are parallel.
