Which of the following is a true statement?
- AOnly a unique line can be drawn through a given point.
- BInfinitely many lines can be drawn through two given points.
- ✓If two circles are equal, then their radii are equal.
- DA line has a definite length.
Answer
View full question & answer→Correct option: C.
If two circles are equal, then their radii are equal.
In option $(a)$, infinite number of line can be drawn to pass through a given point. So, it is not a true statement.
In option $(b)$, only one line can be drawn to pass through two given points. So, it is not a true statement.
In option $(c)$,
'If two circles are equal, then their radii are equal' is the true statement.
In option $(d)$, A line has no end points. A line has an indefinite length. So, it is not a true statement.
In option $(b)$, only one line can be drawn to pass through two given points. So, it is not a true statement.
In option $(c)$,
'If two circles are equal, then their radii are equal' is the true statement.
In option $(d)$, A line has no end points. A line has an indefinite length. So, it is not a true statement.

Which of the following is a true statement?
- AThe floor and a wall of a room are parallel planes.
- BThe ceiling and a wall of a room are parallel planes.
- ✓The floor and the ceiling of a room are parallel planes.
- DTwo adjacent walls of a room are parallel planes.
Answer
View full question & answer→Correct option: C.
The floor and the ceiling of a room are parallel planes.
Two lines are said to be parallel, if they have no point in common.
Options $(a), (b)$ and $(d)$ have a common point, hence they are not parallel.
In option $(c)$, the floor and the ceiling of a room are parallel to each other is a true statement.
Options $(a), (b)$ and $(d)$ have a common point, hence they are not parallel.
In option $(c)$, the floor and the ceiling of a room are parallel to each other is a true statement.

MCQ 91 Mark
Which of the following is a false statement?
- AAn infinity number of lines can be drawn to pass through a given point.
- BA unique line can be drawn to pass through two given points.
- ✓$\text{Ray }\overrightarrow{\text{AB}}=\text{ray}\ \overrightarrow{\text{BA}}.$
- DA ray has one end point.
Answer
View full question & answer→Correct option: C.
$\text{Ray }\overrightarrow{\text{AB}}=\text{ray}\ \overrightarrow{\text{BA}}.$
Option $(a)$ is true, since we can pass an infinite number of lines through a given point.
Option $(b)$ is true, since a unique line can be drawn to pass through two given points.
Consider option $(c)$.
A ray is a line segment that extends indefinitely in one direction as shown below.
$\text{Ray }\overrightarrow{\text{AB}}=\text{ray}\ \overrightarrow{\text{BA}}$ is a false statement since clearly the lines extend indefinitely.
As shown in the above diagram, a ray has only one end-point. So, option $(d)$ is true.
Hence, the only false statement is option $(c)$.
Option $(b)$ is true, since a unique line can be drawn to pass through two given points.
Consider option $(c)$.
A ray is a line segment that extends indefinitely in one direction as shown below.
$\text{Ray }\overrightarrow{\text{AB}}=\text{ray}\ \overrightarrow{\text{BA}}$ is a false statement since clearly the lines extend indefinitely.
As shown in the above diagram, a ray has only one end-point. So, option $(d)$ is true.
Hence, the only false statement is option $(c)$.

MCQ 171 Mark
A is of the same age as $B$ and $C$ is of the same age as $B$. Euclid's which axiom illustrates the relative ages of $A$ and $C$?
- ✓Frist axiom.
- BSecond exiom.
- CThird axiom.
- DFourth axiom.
Answer
View full question & answer→Correct option: A.
Frist axiom.
Euclid's first axiom states that 'Things which are equal to the same thing are equal to one another'.
That is,
$A'$s age = $B'$s age and $C'$s age = $B'$ age
$\Rightarrow A'$s age = $C'$s age
That is,
$A'$s age = $B'$s age and $C'$s age = $B'$ age
$\Rightarrow A'$s age = $C'$s age
