# How many sides is a quadrilateral?

## How many sides is a quadrilateral?

four sides
A quadrilateral is a polygon with four sides. There are many special types of quadrilateral. A parallelogram is a quadrilateral in which both pairs of opposite sides are parallel .

## Does a quadrilateral have to have equal sides?

The only regular (all sides equal and all angles equal) quadrilateral is a square. So all other quadrilaterals are irregular.

What is a quadrangle in math?

A plane figure consisting of four points, each of which is joined to two other points by a line segment (where the line segments may intersect). A quadrangle may therefore be concave or convex; if it is convex, it is called a quadrilateral.

### Are all trapezoids quadrangles?

A quadrangle is a shape with four angles. All quadrangles are quadrilaterals. There are six different types of quadrangles: trapezoid, kite, parallelogram, rhombus, rectangle, and square.

### Does a rhombus have 4 right angles?

If you have a rhombus with four equal interior angles, you have a square. A square is a special case of a rhombus, because it has four equal-length sides and goes above and beyond that to also have four right angles. Every square you see will be a rhombus, but not every rhombus you meet will be a square.

What do you call a shape with 4 unequal sides?

Quadrilaterals are polygons with four sides (hence the beginning “quad”, which means “four”). A polygon with non-equal sides is called irregular, so the figure that you are describing is an irregular quadrilateral.

## What are some examples of a quadrangle?

Nine different shapes are examples of quadrangles:

• Trapezium.
• Trapezoid.
• Isosceles trapezoid.
• Kite.
• Dart.
• Parallelogram.
• Rectangle.
• Rhombus.
