## Important topics for RD Sharma Class 8 Maths Solutions Chapter 17: Understanding Shapes (Special Types of Quadrilaterals)

In mathematics, a quadrilateral is defined as a polygon with four sides. RD Sharma Class 8 Maths Chapter 17 discusses the properties of quadrilaterals in detail. Let us revise them quickly.

1. Rectangle: A quadrilateral in which the opposite sides are parallel to each other, and all the sides are perpendicular to each other. Thus, all the interior angles of a rectangle measure 90°. The diagonals of a rectangle are of equal length.
2. Square: A type of quadrilateral with all the four sides equal. In this, diagonals bisect each other at an angle of 90°.
3. Parallelogram: It is a quadrilateral in which opposite sides are parallel and equal.

Other properties of a parallelogram are:

• The opposite angles of a parallelogram are of equal measure.
• The adjacent angles in a parallelogram are supplementary.
•  The diagonals of a parallelogram bisect each other.

• Rombus: It is a special type of parallelogram, but all sides are equal. Some properties include:
1. The diagonals of a rhombus are perpendicular bisectors of one another.
2. In a rhombus ABCD with O as intersection point, OA = OC and OB = OD
• Trapezium: In this, only one pair of the four sides are parallel to each other.

Some other essential points to remember:

• The sum of the measures of the four angles of a convex quadrilateral is 360°
• n – 2 provides the number of triangles in a polygon.
• Sum of interior angles of n-sided polygon = (n-2)X180°
• an exterior angle of a polygon = 360 ÷ number of sides
