Quadrilaterals Introduction

A quadrilateral is a figure that has four (4) sides or edges and also has four vertices or corners. Quadrilaterals will typically be of regular shapes with four sides like square, rectangle, trapezoid, and kite.

A quadrilateral can be described as a closed, two-dimensional pattern that has four straight edges. The polygon has four corners or vertices. We can obtain the shape of quadrilaterals in different things around us, such as a chessboard, a kite, a deck of cards, a signboard, a tub of popcorn, and an arrow.

Quadrilaterals consecutive or adjacent sides

There are four vertices in a quadrilateral, but every vertex is created by connecting the endpoints of two edges. The two edges of the quadrilateral are known as the adjacent sides or consecutive sides of a quadrilateral.

Opposite Sides of a Quadrilateral

Two sides or edges of a quadrilateral are known as opposite sides or edges if they do not have a constant endpoint.

Quadrilaterals Consecutive/ Adjacent Angles

Two angles of a quadrilateral having a constant arm are known as its adjacent angles.

Quadrilaterals Opposite Angles

Two angles of a quadrilateral, which are not consecutive/ adjacent angles, are called the opposite angles.

Angle Sum Property of a Quadrilaterals

A quadrilateral is a polygon with four (4) vertices, four (4) sides, four (4) angles, and all the angles are 360°. When we draw the diagonals to the quadrilateral, it makes two triangles. Both particular triangles have an angle total of 180°. Therefore, the cumulative angle sum of the quadrilateral is 360°. Angle sum is one of the attributes of quadrilaterals.

Frequently Asked Questions (FAQs) of RD Sharma Chapter 14 Class 9 Maths Exercise 14.1 Solutions

Ques 1- What is the sum of four angles of the quadrilateral?

Ans- The sum of four angles of the quadrilateral is 360°.

Ques 2- What is the formula of angle sum property?

Ans- The formula for the angle sum property is-

S = ( n − 2) × 180°

“n” signifies the number of sides or edges of the quadrilateral.
