Types of Quadrilaterals
(i) LM is parallel to ON.
2. Rectangle:A rectangle is a parallelogram in which all the angles are right angles.
Here ABCD is a rectangle.
(i) So, AB is parallel to DC.
3. Square:A square is a rectangle in which all sides are equal.
Here ABCD is a square.
(i) AB is parallel to DC.
4. Rhombus:A rhombus is a parallelogram whose all sides are equal, opposite sides are parallel and opposite angles are equal.
Here LMNO is a rhombus.
(i) LM = MN = NO = OL
5. Trapezium:A quadrilateral is called trapezium if a pair of its opposite sides are parallel.
Here ABCD is a trapezium.
AB is parallel to DC
If a trapezium has non parallel sides equal, it is called isosceles trapezium.
Let’s discuss about the properties of types of quadrilateral in the table below;
