Identify closed curve from the given figures.

0%
$1$ only
0%
$1 ,2$ only
0%
$1,2,3$ only
0%
$4$ only

Explanation

We know that an open curve has two end points and a closed curve has no end points because its starting and ending points are same.

Therefore the figure

$1,2,3$ are the open figures whereas

$4$ is a closed figure.

Hence only

$4$ is a closed figure which is a circle.

Consider the given figure of line

$\overleftrightarrow{MN}$ . Say whether following statement is True or False in context of the given figure.
O and N are end points of line segment

$\overline{OP}$ .

0%
True
0%
False

Explanation

Step 1: False

In the line segment

$\overline{OP},$

$O$ and

$P$ are the end points.

Hence, given statement is false.

State true or false:
A line segment has one end point only.

0%
True
0%
False

State true or false:
A segment has no length.

0%
True
0%
False

Explanation

Suppose P and Q are the two points, then the line segment

$PQ$ can be measured. Thus the line segment has fixed length.

Hence, given statement is false.

If the sum of the circumferences of two circles with radii

$R_1$ and

$R_2$ is equal to the circumference of a circle of radius

$R$ , then

0%
$R_{1}+R_{2}=R$
0%
$R_{1}+R_{2}>R$
0%
$R_{1}+R_{2} < R$
0%
Nothing definite can be said about the relation among $R_1, R_2$ and R.

Explanation

The circumference of circle with radius

${ R }_{ 1 }=2\pi { R }_{ 1 }$ .

and the circumference of circle with radius

${ R }_{ 2 }=2\pi { R }_{ 2 }.$

$\therefore$ The Sum of Circumferences,

$Sum=2\pi \left( { R }_{ 1 }+{ R }_{ 2 } \right)$ .

Again the circumference of circle with radius

${ R }=2\pi { R }.$

$\therefore$ By given condition,

$2\pi \left( { R }_{ 1 }+{ R }_{ 2 } \right) =2\pi { R }\Longrightarrow { R }_{ 1 }+{ R }_{ 2 }=R$ .

Which of the following statement is false?

0%
If we join any two points on a circle we get a diameter of the circle
0%
A diameter of a circle contains the centre of the circle
0%
A semicircle is an arc
0%
The length of a circle is called its circumference

Explanation

$\textbf{Step - 1: Verify, If we join any points on a circle we get a diameter of the circle}$

$\text{A Chord is a line segment that joins any two points of the circle.}$

$\text{The endpoints of this line segments lie on the circumference of the circle.}$

$\therefore \text{Option (A) is false}$

$\textbf{Step - 2: Verify, A diameter of a circle contains the center of the circle}$

$\text{Any interval joining two points on the circle and passing through the center is called a}$

$\text{diameter of the circle.}$

$\therefore \text{Option (B) is True}$

$\textbf{Step - 3: Verify, A semicircle is an arc}$

$\text{The arc of a circle consists of two points on the circle and all of the points on the circle that lie}$

$\text{between those two points.}$

$\text{It's like a segment that was wrapped partway around a circle.}$

$\text{An arc whose measure equals 180 degrees is called a semicircle since it divides the circle in two}$

$\therefore \text{Option (C) is True}$

$\textbf{Step - 4: Verify, the length of a circle is called its circumference}$

$\text{A Circle is a round closed figure where all its boundary points are equidistant from a fixed point}$

$\text{called the center.}$

$\text{The two important metrics of a circle is the area of a circle and the circumference of a circle.}$

$\therefore \text{Option (D) is True}$

$\textbf{Hence, option A is correct as it is false}$

Which of the following is different from the other three?

Explanation

From the given figures we can see that,

$\Rightarrow$ Option

$A$ has five sides, so its a pentagon

$\Rightarrow$ So, Option

$B, C$ and

$D$ are types of quadrilateral.

$\Rightarrow$ Thus we can prove that option A is different from the other three.
