Class 8 Understanding Quadrilaterals

1. Properties of Different Quadrilaterals
A quadrilateral is a polygon with four sides and four angles. There are different types of quadrilaterals and
all of them show different properties as mentioned below.
1. Parallelogram
• Opposite sides parallel
• Opposite sides equal
• Opposite angles equal
• Diagonals bisect each other
2. Rectangle
• Opposite side parallel
• Opposite sides equal
• Opposite angles equal
• Diagonals bisect each other
• Diagonals equal
• Four right angles

2. 3. Rhombus
• Opposite side parallel
• Opposite sides equal
• Opposite angles equal
• Diagonals bisect each other
• Diagonals are perpendicular
• Four equal sides
4. Square
• Opposite side parallel
• Opposite sides equal
• Opposite angles equal
• Diagonals bisect each other
• Diagonals equal
• Diagonals are perpendicular
• Four right angles
• Four equal sides
5. Trapezium
• 1 pair opposite sides parallel
• 1 pair opposite sides equal
6. Kite
If the two pairs of adjacent sides are equal
in a quadrilateral then it is called a Kite.
Here AB = BC and AD = CD
• Diagonals are perpendicular
