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

The edge of a notebook can be considered as

A.

Ray

B.

Line Segment

C.

Line

D.

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.

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

A.

2,2

B.

2,4

C.

4,2

D.

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.

Find the number of triangles in the given figure. A.

4

B.

6

C.

5

D.

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.

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

Sector, Arc

B.

Segment, Arc

C.

Segment, Sector

D.

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.

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

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

B.

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

C.

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

D.

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

A note book has __ edges.

#### SOLUTION

Solution :

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

A triangle is a polygon with __ sides.

#### SOLUTION

Solution :

A triangle is 3 sided polygon.

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.

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.

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

A.

True

B.

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.
