## Understanding Quadrilaterals Class 8 Maths Formulas

**Polygon**: A polygon is a closed figure bounded by three or more line segments such that each line segment intersects exactly two other points (vertices) as shown in the following figures.**Quadrilateral**: A simple closed figure bounded by four line segments is called a quadrilateral, it has four sides, i.e., AB, BC, CD and AD and four vertices as A, B, C and D and the sum of all angles of a quadrilateral is 360°.**Parallelogram**: A quadrilateral in which opposite sides are parallel and equal is called parallelogram; written as || gm. and the diagonals of a parallelogram bisect each other.**Properties of parallelogram:**- Opposite angles are equal.
- Diagonals bisect each other.
- Opposite sides are equal and parallel.

**Curve**: A figure formed on a plane surface by joining a number of points without lifting a pencil is called a curve.**Open Curve**: A curve which does not end at the same starting point or which does not cut itself is called an open curve.**Closed Curve**: A curve which cut itself or which starts and ends at the same point is called a closed curve.**Simple Closed Curve**: A closed curve called a simple closed curve which does not intersect itself.**Rectangle**: A parallelogram each of whose angle is 90° and diagonals are equal, is called a rectangle.Properties:

- Opposite sides are equal and parallel.
- Each angle is a right angle.
- Diagonals are equal.
- Diagonals bisect each other.

**Square**: A quadrilateral in which all sides and angles are equal, is called a square.**Rhombus**: A parallelogram having all its sides equal, is called a rhombus.**Trapezium**: A quadrilateral in which two opposite sides are parallel and the other two opposite sides are non-parallel, is called a trapezium. If two non-parallel sides of a trapezium are equal, then it is called an isosceles trapezium.Also Read,
