parallelogram
Rectangle, possibly a square if the adjacent sides are also equal.
A rectangle
this would be a rhombus. rhombuses are parallelograms (four-sided shapes with opposite sides parallel) that have all equal side lengths. squares are included as rhombuses.
Parallelogram and rectangle apex
False maybe
A rectangle (including squares). A quadrilateral has four sides. Think of the top and bottom of rectangles - they run parallel, as do the sides.
It is a trapezoid that has only one pair of opposite parallel lines of different lengths.
No, it doesn't have to be. A quadrilateral can definitely be a parallelogram only if: - Both pairs of opposite sides are parallel. - Both pairs of opposite sides are congruent. - One pair of opposite sides are both congruent and parallel. - Both pairs of opposite angles are congruent. - The diagonals bisect each other.
Parallelogram and a rectangle
square
Quadrilaterals that have parallel opposite sides (assuming that each side is parallel to its opposite): A parallelogram A rectangle A square (really a rectangle with all sides equal in length)
Yes, sides are equal in length as well.
