#### Quadrilaterals

A quadrilateral in mathematical terms as a four sided simple closed figure lying in a plane.

Quadrilaterals are geometrical figures that are commonly found in our surroundings. If you look around, you will find a quadrilateral in one form or the other such as, square, rectangle, parallelogram, trapezium, rhombus etc.

Look around while sitting in your drawing room and Image

observe that the ceiling, the table-top, the floor, the door etc.

all suggest quadrilaterals.

##### Definition of a Quadrilateral

Let A, B, C, D be four points in a plane such that no three of them are collinear and the line segments AB, BC, CD and DA do not intersect except at their end points. Then, the figure made of these four line segments is called the quadrilateral ABCD.

### Class 6 Maths Exercise 5.6 Important Extra Questions

### what are the diagonals of a quadrilateral?

The two line segments joining opposite vertices of quadrilateral are called its diagonals.

### Define adjacent sides of a quadrilateral.

Two sides of a quadrilateral which have a common end point are called its adjacent sides.

### Define adjacent angles of a quadrilateral.

Two angles of a quadrilateral having a common side are called its adjacent angles.

### what are the opposite sides of a quadrilateral?

Two sides of a quadrilateral are called its opposite sides, if they do not have a common end point.

##### Terms Related to a Quadrilateral

(i) In the quadrilateral ABCD, the four points A, B, C and D are called its vertices.

(ii) In the quadrilateral ABCD, the four line segments AB, BC, CD and DA are called its sides.

(iii) âˆ DAB, âˆ ABC, âˆ BCD and âˆ CDA are called its angles to be denoted by âˆ A, âˆ B, âˆ C and âˆ D respectively.

(iv) The two line segments AC and BD joining opposite vertices are called its diagonals.

(v) Two sides of a quadrilateral which have a common end point are called its adjacent sides. In Fig., BC, CD; CD, DA; DA, AB and AB, BC are the four pairs of adjacent sides of the quadrilateral ABCD.

(vi) Two sides of a quadrilateral are called its opposite sides, if they do not have a common end point. In Fig., AB, DC and BC, AD are two pairs of the opposite sides of the quadrilateral ABCD.

(vii) Two angles of a quadrilateral having a common side are called its adjacent angles. In Fig., âˆ A, âˆ B; âˆ B, âˆ C; âˆ C, âˆ D and âˆ D, âˆ A are the four pairs of adjacent angles of the quadrilateral ABCD.

(viii) Two angles of a quadrilateral which are not adjacent angles are known as the opposite angles of the quadrilateral.

In Fig., âˆ A, âˆ C and âˆ B, âˆ D are two pairs of opposite angles in quadrilateral ABCD.

### What types of triangles do students study in exercise 5.6 of class 6th Maths?

Types of triangles that students study in exercise 5.6 of grade 6th Maths are:

- Scalene triangle (A triangle having all three unequal sides)
- Equilateral triangle (A triangle having three equal sides)
- Isosceles triangle (A triangle having two equal sides)
- Acute angled triangle (If each angle is less than 90Â°, then the triangle is called an acute-angled triangle.)
- Right-angled triangle (If any one angle is a right angle then the triangle is called a right-angled triangle.)
- Obtuse angled triangle (If any one angle is greater than 90Â°, then the triangle is called an obtuse-angled triangle.)

### Which questions of exercise 5.6 of class 6th Maths may the teacher give in the exams?

Exercise 5.6 of class 6th Maths has only four questions. Questions 1 and 3 are important and have more chance to come in the school exams. Questions 1 and 3 both have 6 parts.
