Weekly Quiz Competition

Question 1
1 / -0

Which of the following has no lines of symmetry ?

A
A scalene triangle

B
An isosceles triangle

C
An equilateral triangle

D
All of these

Solution

$$\Rightarrow$$ An equilateral triangle has three lines of symmetry.
$$\Rightarrow$$ An Isosceles triangle has one line of symmetry.
$$\Rightarrow$$ A scalene triangle does not have any line of symmetry.
$$\therefore$$ Correct answer is option $$A$$.
Question 2
1 / -0

The clock shows the time in the morning. Then, angle represents _________ angle.

A
Acute

B
Obtuse

C
Reflex

D
Straight

Solution

Any angle which is larger than $$180^o$$ but smaller than $$360^o$$ is called as a reflex angle.
Here, the angle shown is larger than $$180^o$$ but smaller than $$360^o$$.
Hence, it is a reflex angle.
Therefore, option $$C$$ is correct.
Question 3
1 / -0

An angle which measures more than $$90^o$$ but less than $$180^o$$ is called ___________.

A
Acute

B
Obtuse

C
Right

D
None of these

Solution

An angle which measures more than $$90^o$$ but less than $$180^o$$ is called as an obtuse angle.
Question 4
1 / -0

What is the approximate measure of this angle in degrees?

A
$$20^o$$

B
$$45^o$$

C
$$110^o$$

D
$$135^o$$

Solution

The given angle is a acute angle, so option D and option C is not correct
The approximate value of above angle is $$45^o$$, as the angle of $$20^o$$ would be very small than the given angle
Hence the correct answer is option B.
Question 5
1 / -0

Which of the following is greater than a right angle?

A

B

C

D

Solution

Option $$A$$- Angle shown is a right angle
Option $$B$$-Angle shown is a acute angle
Option $$C$$-Angle shown is a acute angle
Option $$D$$-Angle shown is an obtuse angle.
Hence option $$D$$ is the correct answer
Question 6
1 / -0

A geometrical figure with eight sides is called

A
polygon

B
hexagon

C
octagon

D
pentagon

Solution

Octagon as Oct a means eight. Hence an octagon has eight sides.
Question 7
1 / -0

Which three dimensional figure has $$5$$ faces, $$8$$ edges and $$5$$ vertices?

A

B

C

D

Solution

A) Rectangular Pyramid-It has $$5$$ faces, $$8$$ edges and $$5$$ vertices.
B) Cube- it has $$6$$ faces, $$12$$ edges and $$8$$ vertices.
C)Cuboid-It has $$6$$ faces, $$12$$ edges and $$8$$ vertices.
D) Cylinder-It has $$3$$ faces, $$2$$ edges and no vertices.
Answer : A
Question 8
1 / -0

Which of these is NOT a 3-dimensional shape?

A
Sphere

B
Cuboid

C
Cube

D
Circle

Solution

Sphere, Cuboid and Cube are $$3$$-D shapes as they are associated with third dimension which is height.
Now, Circle is $$2$$-D shape as it can has only two dimensions.
Question 9
1 / -0

$$p :$$ The corners of a solid shape are called its edges.
$$q :$$ The line segments of a solid shape are called its vertices.
Which of the following options hold?

A
Both $$p$$ and $$q$$ are true

B
$$p$$ is true and $$q$$ is false

C
Both $$p$$ and $$q$$ are false

D
$$p$$ is false and $$q$$ is true

Solution

Edges are the line segments which make the sides of a solid shape, whereas, vertex is the corner of a solid shape, the point where edges meet.

Hence, both $$p$$ and $$q$$ are false.
Question 10
1 / -0

If each pair of opposite sides of a quadrilateral are equal and parallel, then it is a ____________.

A
Kite

B
Trapezium

C
Parallelogram

D
None of these

Solution

if each pair of opposite sides of a quadrilateral is equal and parallel then it is a parallelogram (property of parallelogram)
