Explanation

We need to count the number of the faces outside, they will be the ones colored red.

There are

$4$ faces each on the front, back, upper and down sides.

And

$1$ faces each on side faces.

So there are in total

$4\times 4 + 2$ , i.e.

$18$ faces coloured red.

At which one of the following times is the angle between the hands of a clock exactly one right angle?

0%
$3$ : $30$
0%
$3$ : $00$
0%
$12$ : $00$
0%
None of these

Explanation

Angle between the hands of clock is exactly right angle at

$3$ :

$00$

So option

$B$ is correct.

How many right angles are there in

$540^o$ ?

0%
$4$
0%
$6$
0%
$8$
0%
none of these

Explanation

One right angle

$=90^{\circ}$

Let there be

$x$ right angles in

$540^{\circ}$

$\Rightarrow { 90 }^{ \circ }x={ 540 }^{ \circ }\\ \Rightarrow x=\dfrac { { 540 }^{ \circ } }{ { 90 }^{ \circ } } =6$

So option

$B$ is correct.

State whether the following statement is true or false?
All right angles are equal

0%
True
0%
False

Explanation

Measure of any right angle is

$90^o$ .Hence all right angles are congruent,

Which statement is false in the following statements?

0%
Rectangle is $2-$ dimension shape
0%
Pyramid is $3-$ dimension shape.
0%
Cone is $2-$ dimension
0%
Circle is $2-$ dimension shape.

Explanation

Cone is

$2-$ dimension. This statement is false. Because cone is

$3-$ dimension.

What is the base of the cone?

0%
Square
0%

None of these

How many degrees are there in one right angle?

0%
$0^o$
0%
$180^o$
0%
$100^o$
0%
None of these

Explanation

Right angle

$=90^{\circ}$

So there are

$90$ degrees in one right angle.

Hence option

$D$ is correct.

A circular paper is divided into

$4$ equal parts by cutting it through two diameters. Then the central angle of each part is equal to:

0%
$45^\circ$
0%
$90^\circ$
0%
$60^\circ$
0%
$30^\circ$

Explanation

Central angle

$=360^{\circ}$

Now circular piece of paper is divided in four equal parts .

Let measure of central angle

$=x$

$\\ \Rightarrow x+x+x+x={ 360 }^{ \circ }\\ \Rightarrow 4x={ 360 }^{ \circ }\\ \Rightarrow x=\dfrac { { 360 }^{ \circ } }{ 4 } \\ \Rightarrow x={ 90 }^{ \circ }$

So option

$B$ is correct.

The angle formed by the pages of an open book is:

0%
Acute
0%
Obtuse
0%
Right
0%
Straight

Explanation

The angle formed by the pages of an open book is obtuse.

Since the angle will always be more than

$90$ but less than

$180$ .

In a triangle

$ABC$ ,

$AB=AC$ , then

$\triangle ABC$ is a/an ............ triangle.

0%
right angled
0%
equilateral
0%
isosceles
0%
scalene

Explanation

Given,

$\triangle ABC, AB = AC$

We know, if two sides of a triangle are equal then the triangle is an isosceles triangle.

Thus,

$\triangle ABC$ is an isosceles triangle.

Hence, option

$C$ is correct.

Let's divide a circle into

$10$ equal parts. Then, the measure of each central angle of a circle is :

0%
$18^{o}$
0%
$72^{o}$
0%
$36^{o}$
0%
$30^{o}$

Explanation

Since, circle divides in 10 equal parts, total measure angle at centre

$=360°$ .

So, each central angle after division is

$=\cfrac{360°}{10}=36°$

1013228_673537_ans_3c86bd97a77448fcbab06aaed601b8c6.png

The central angle of each part is:

0%
$60^\circ$
0%
$30^\circ$
0%
$45^\circ$
0%
$90^\circ$

Explanation

You can clearly see the circle is divided into

$12$ equal parts.

Total Central angle

$=360^{\circ}$

Let measure of central angle

$=x$

$\\ \Rightarrow 12(x)={ 360 }^{ \circ }\\ \Rightarrow 12x={ 360 }^{ \circ }\\ \Rightarrow x=\dfrac { { 360 }^{ \circ } }{ 12 } \\ \Rightarrow x={ 30 }^{ \circ }$

So option

$B$ is correct.
