The corners and mid-points of the sides of a triangle are named using the distinct letters $\text{P, Q, R, S, T}$ and $\text{U,}$ but not necessarily in the same order. Consider the following statements:

  • The line joining $\text{P}$ and $\text{R}$ is parallel to the line joining $\text{Q}$ and $\text{S}.$
  • $\text{P}$ is placed on the side opposite to the corner $\text{T}.$
  • $\text{S}$ and $\text{U}$ cannot be placed on the same side.

Which one of the following statements is correct based on the above information?

  1. $\text{P}$ cannot be placed at a corner
  2. $\text{S}$ cannot be placed at a corner
  3. $\text{U}$ cannot be placed at a mid-point
  4. $\text{R}$ cannot be placed at a corner

Given that, the following statements:

  • The line joining $\text{P}$ and $\text{R}$ is parallel to the line joining $\text{Q}$ and $\text{S}.$
  • $\text{P}$ is placed on the side opposite to the corner $\text{T}.$
  • $\text{S}$ and $\text{U}$ cannot be placed on the same side.

Based on the above statements, we can draw the diagram.

We can also change the position of $\text{Q, S}$ and $\text{P, R}.$

Now we can check all the options.

  1. $\text{P}$ cannot be placed at a corner ${\color{Red}{-\text{False}}}$
  2. $\text{S}$ cannot be placed at a corner ${\color{Green}{-\text{True}}}$
  3. $\text{U}$ cannot be placed at a mid-point ${\color{Red}{-\text{False}}}$
  4. $\text{R}$ cannot be placed at a corner ${\color{Red}{-\text{False}}}$

Correct Answer $:\text{B}$
