# Free Basic Geometrical Ideas 03 Practice Test - 6th grade

### Question 1

The edge of a notebook can be considered as

Ray

Line Segment

Line

Collection of Points

#### SOLUTION

Solution :B

As you can see, it forms a line segment. A line segment is a part of a line which has two end points.

### Question 2

The edges of the top of a rectangular table form ___ pair of parallel lines and intersect at _____ different points.

2,2

2,4

4,2

4,4

#### SOLUTION

Solution :B

In above table, sides AB ll CD and AD ll BC.

So, there are two pairs of parallel lines in the rectangular table.

A is the point of intersection of lines BA & AD.

B is the point of intersection of lines AB & BC.

C is the point of intersection of lines BC & CD.

D is the point of intersection of lines AD & DC.

Hence they intersect at 4 different points.

### Question 3

Find the number of triangles in the given figure.

4

6

5

3

#### SOLUTION

Solution :B

Given that,

the figure as shown below:

Now,

on counting the number of triangles

in the given figure:

ΔBAD, Δ BAE, ΔBAC, ΔDAE, ΔDAC and ΔEAC.So, there are 6 triangles are there in the shown figure.

### Question 4

In the below figure, the shaded region I represents a ______ and region II represents a ______.

Sector, Arc

Segment, Arc

Segment, Sector

Sector, Segment

#### SOLUTION

Solution :D

A region in the interior of a circle enclosed by an arc on one side and a pair of radii on the other two sides is called a sector. So, region I is a sector.A region in the interior of a circle enclosed by a chord and an arc is called a segment of the circle. So, region II is a segment.

Hence, region I shows a sector and region II shows a segment.

### Question 5

Identify radius, centre, chord and diameter in the given circle.

Radius-AB ; Chord-BC ; Diameter -OA ; Centre-O

Radii-OA,OC,OB ; Chord-BC ; Diameter-AB ; Centre-O

Radius-AC ; Chord- OA,OB,OC ; Diameter-AB ; Centre-O

Radii-OA,OC ; Chord-BC ; Diameter-AC ; Centre-O

#### SOLUTION

Solution :B

From the above figure we can find

Radii :-OA,OC and OB ;

Chord :-BC ;

Diameter :-AB and

Centre :- O

### Question 6

A note book has

#### SOLUTION

Solution :Line segment has two definite ends. A notebook has 12 line segments which is eventually sides of a notebook.

### Question 7

A triangle is a polygon with

#### SOLUTION

Solution :A triangle is 3 sided polygon.

### Question 8

Using a sharp tip of the pencil, mark a dot on the paper. This dot is called a

#### SOLUTION

Solution :A point is a basic geometric shape that has zero dimension. A point in geometry determines location.

### Question 9

If a line segment is extended in both the directions then we will get a

#### SOLUTION

Solution :If a line segment is extended in both the directions, then we will get a line.

### Question 10

A star in the sky can be considered as a point.

True

False

#### SOLUTION

Solution :A

When we look at a star in the sky, it appears like a point in the sky. Hence it can be compared to a point.
