# Which Quadrilateral Has Opposite Sides Parallel?

If you’re studying geometry, you’ll want to know which quadrilateral has opposite sides parallel. A quadrilateral is a four sided shape, and when it has opposite sides parallel, it is called a parallelogram. So, which quadrilateral has opposite sides parallel? The answer is: a few different types of quadrilaterals.

## Parallelograms

Parallelograms are quadrilaterals with two pairs of parallel sides. They can come in a variety of shapes, including rectangles, rhombuses, and squares. All parallelograms have opposite sides that are equal in length, and the angles between each set of opposite sides are equal.

### Rectangles

One type of parallelogram is the rectangle. In a rectangle, all four sides are equal in length, and the angles between each set of opposite sides are 90 degrees. Rectangles are the most common type of parallelogram and are used in many everyday applications, such as the frames of doors and windows.

### Rhombuses

Another type of parallelogram is the rhombus. A rhombus is similar to a rectangle, but all four sides are not equal in length. The angles between each set of opposite sides are still equal, however, and the angle between each set of opposite sides is usually around 90 degrees.

### Squares

The last type of parallelogram is the square. A square is similar to both a rectangle and a rhombus, but all four sides are equal in length. The angles between each set of opposite sides are 90 degrees, just like a rectangle.

## Trapezoids

Trapezoids are another type of quadrilateral with two pairs of parallel sides. In a trapezoid, the two parallel sides are called the bases, and the other two sides are called the legs. The angles between the bases and the legs are not equal, and the length of the legs can vary.

## Kites

The final type of quadrilateral with opposite sides parallel is the kite. A kite is a four-sided shape with two sets of adjacent sides that are equal in length. The other two sides, which are opposite each other, are both equal in length and parallel to each other.

## Conclusion

So, which quadrilateral has opposite sides parallel? The answer is: a few different types of quadrilaterals. Parallelograms, trapezoids, and kites all have two pairs of parallel sides. Parallelograms include rectangles, rhombuses, and squares, which all have four equal sides and angles between each set of opposite sides. Trapezoids have two parallel sides that are called the bases, and the other two sides are called the legs. Lastly, kites have two sets of adjacent sides that are equal in length, and the other two sides are both equal in length and parallel to each other.
