What is a quadrilateral?
|
Answer: A quadrilateral is defined as any two-dimensional, four-sided shape that has four vertices with interior angles that equal 360 degrees. There are several quadrilateral variations that include parallelograms, rectangles, rhombuses, squares, trapezoids, and kites.
Quadrilaterals
- Parallelogram – A parallelogram consists of two pairs of parallel sides. Opposite angles are equal. Rectangles, rhombuses, and squares are also considered parallelograms.
- Rectangle – A rectangle has four sides; each side is a right angle (90°).
- Rhombus – A rhombus has four sides, each one being of equal length and parallel to the opposite side. A rhombus with all right angles is a square.
- Square – A square has four equal sides and four equal angles (90°).
- Kite – A kite is a quadrilateral with two pairs of equal length, adjacent sides.
- Trapezoid – A trapezoid is a quadrilateral that consists of 2 parallel sides.
