**Brilliant’s Composite Mathematics Class 6 Solutions Chapter 10 Basic Geometrical Concepts**

Welcome to NCTB Solutions. Here with this post we are going to help 6th class students for the Solutions of Brilliant’s Composite Mathematics Class 6 Math Book, Chapter 10, Basic Geometrical Concepts. Here students can easily find step by step solutions of all the problems for Basic Geometrical Concepts, Exercise Questions. Also here our mathematics teacher’s are solved all the problems with easily understandable methods with proper guidance so that all the students can understand easily.

**Basic Geometrical Concepts Exercise Solution**

**(a)** A dot on a paper by a shape pencil

**(b)** A corner of a box or a table or a book

**(c)** The tip of a needle, or a pen.

**(ii)** **Three examples of Portion of a line:**

**(a)** Two points meet, draw a paper.

**(b)** take a pile of thread and hold it by two ends

**(c)** Side of a book.

**(iii)** **Three examples of Portion of a plane :**

**(a)** The surface of a page

**(b)** Top of a study table

**(c)** Surface of a black board .

**(iv) Three examples of Plane surface :**

**(a)** The surface of a paper

**(b)** Top of a table

**(c)** Surface of a black board.

**Question no – (2)**

**Solution :**

Required Line :

Line name = AB

**Question no – (3)**

**Solution :**

No, we cannot draw a line on the surface of a sphere which lies wholly on it.

**Question no – (4)**

**Solution :**

**(a)** Infinite lines can draw through a point.

**(b)** Only one line can draw through two points.

**Question no – (5)**

**Solution :**

There lines can be draw through three non collinear points.

**Question no – (6)**

**Solution :**

**(A)** Maximum number of points of intersection of three lines in a plane is 3

**(B)** Minimum number of points of intersection of three lines in a plane is 0

**Question no – (7) **

**Solution :**

**(i) Four examples of intersecting lines are –**

**(a)** A pair of scissors

**(b)** plus

**(c)** The letter X of English alphabet.

**(d)** Crossing roads.

**(ii)** **Four examples of Parallel lines are –**

**(a)** Truck of a railway.

**(b)** opposite line of a rectangle field.

**(c)** opposite edge of a cube.

**(d)** sides of road.

**Question no – (8) **

**Solution :**

**Collinear points :**

Three or more points in a plane which lie or the same line are called Collinear points.

Only one line can be drawn through three collinear points.

**Question no – (9)**

**Solution :**

**Concurrent lines :**

Three or more lines in a plane are said to be concurrent if all them pass through the same point.

AD, BE and CF are in concurrent.

H is their point of concurrence.

**Question no – (10)**

**Solution :**

**Parallel lines :**

Two straight lines which are in the same plane and do not meet , however far , they are produced in both the directions are called Parallel lines.

**Four examples of parallel lines are –**

**(i)** Track of railway line

**(ii)** Opposite line of a rectangle.

**(iii)** Opposite edge of a cube

**(iv)** Side of roads.

**Question no – (11)**

**Solution :**

**Four points are –**

A AB, AC,BC,BD,DC and DA

Six different line can be drawn.

The lines which are concurrent at A are –

AB, AC, AD are concernment at A

**Question no – (12)**

**Solution :**

**(i)** Four pairs of intersecting lines.

= l , p , r ; m, r ; and m , a .

**(ii) **Lines which are parallel to m.

= l, n are parallel to m .

**(iii)** Lines whose point of concurrence is A .

concurrence in A are –

= l , r , and p

**(iv)** Lines whose point of intersection is H.

= lines m and q.

**(v)** Three sets of collinear points

= A,B, and C , K , E and H and B , D and E.
