A quadrilateral has: 1. four sides (edges) 2. four vertices (corners) 3. interior angles that add to 360 degrees: Try drawing a quadrilateral, and measure the angles. They should add to 360°
There are special types of quadrilateral: Some types are also included in the definition of other types! For example a square, rhombus and rectangle are also parallelograms. See belowfor more details. Let us look at each type in turn:
the little squares in each corner mean "right angle" A rectangle is a four-sided shape where every angle is a right angle(90°). Also opposite sides are paralleland of equal length.
the little squares in each corner mean "right angle" A squarehas equal sides (marked "s") and every angle is a right angle (90°) Also opposite sides are parallel. A square also fits the definition of a rectangle (all angles are 90°), and a rhombus(all sides are equal length).
A rhombusis a four-sided shape where all sides have equal length (marked "s"). Also opposite sides are parallel andopposite angles are equal. Another interesting thing is that the diagonals (dashed lines) meet in the middle at a right angle. In other words they "bisect" (cut in half) each other at right angles. A rhombus is sometimes called a rhomb...
A parallelogramhas opposite sides parallel and equal in length. Also opposite angles are equal (angles "A" are the same, and angles "B" are the same).
A trapezoid (called a trapezium in the UK)has a pair of opposite sides parallel. And a trapezium (called a trapezoid in the UK)is a quadrilateral with NO parallel sides: An Isoscelestrapezoid, as shown above, has left and right sides of equal length that join to the base at equal angles.
Hey, it looks like a kite(usually). It has two pairsof sides: Each pair is made of two equal-length sides that join up. Also: 1. the angles where the two pairs meet are equal. 2. the diagonals, shown as dashed lines above, meet at a right angle. 3. one of the diagonals bisects(cuts equally in half) the other. ... and that's it for the special quadr...
The only regular (all sides equal and all angles equal) quadrilateral is a square. So all other quadrilaterals are irregular.
Quadrilateral definitions are inclusive. This may seem odd, as in daily life we think of a square as not being a rectangle ... but in mathematics it is. Using the chart below we can answer such questions as: 1. Is a Square a type of Rectangle? (Yes) 2. Is a Rectangle a type of Kite? (No)

In Euclidean geometry, an isosceles trapezoid (isosceles trapezium in British English) is a convex quadrilateral with a line of symmetry bisecting one pair of opposite sides. It is a special case of a trapezoid .

A trapezoid: has a pair of parallel sides. is an isosceles trapezoid when it has equal angles from a parallel side. is called a " trapezium " in the UK (see below) Play with a trapezoid: The parallel sides are the "bases". The other two sides are the "legs".
