A rectangle is a parallelogram, and neither a trapezoid nor an isosceles trapezoid could have exactly two opposite right angles.
So, a quadrilateral that is not a parallelogram and could have exactly two opposite right angles must be a kite.

Why is a trapezoid also a parallelogram?
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.
How many congruent triangles make a parallelogram?
Answer: 2 Explanation: A parallelogram is a quadrilateral which has both pairs of the opposite sides parallel. Congruent triangles are triangles that have exactly the same three sides and exactly the same three angles. So, in a parallelogram, each diagonal divides it in 2 congruent triangles.

Which quadrilateral shows exactly two pairs of parallel sides?
parallelogram, rectangle, square -_-
Does every quadrilateral have exactly 4 sides?
Yes, by definition a quadrilateral has four sides.
What is a quadrilateral with exactly 1 pair of opposite sides that is parallel?
a trapizoid
What type of quadrilateral has exactly one pair of parallel sides is it a parallelogram?
It is a trapezoid that has one pair of opposite parallel sides of different lengths whereas a parallelogram has two pairs of parallel sides.

A quadrilateral has exactly two congruent angles?
A parallelogram has 2 pairs of congruent angles of different sizes
What is a quadrilateral with exactly 1 pair of opposite sides that is parallel?
a trapizoid
What quadrilateral has exactly one pair of opposite sides are parallel?
A trapezoid.
What quadrilateral has exactly one pair of opposite angels are congruent?
Kite
What is quadrilateral with exactly one pair of opposite sides that are parallel?
A trapezoid
What characteristics help you classifly a quadrilateral as a parallelogram and not a rectangle?
A rectangle has four interior angles that are exactly 90 degrees. A parallelogram can have two opposite angles larger than 90 and the other two, smaller than 90 degrees but still add up to 360 degrees.
Can a trapezoid have more than 4 sides?
No, a trapezoid, by definition, is a quadrilateral with exactly one pair of parallel sides. Therefore, it can only have four sides.
