[Done] Write a paragraph proof of this theorem: In a plane, if two lines are perpendicular to the same line, then they are parallel to each other. Given: \( R \perp S \), \( T \perp S \) Prove: \( R \parallel T \) Proof: Since line \( R \) is perpendicular to line \( S \), and line \( T \) is also perpendicular to line \( S \), both lines \( R \) and \( T \) form right angles with line \( S \). According to the definition of perpendicular lines, both \( R \) and \( T \) create a \(90^\circ\) angle with line \( S \). By the converse of the Alternate Interior Angles Theorem, if two lines are cut by a transversal and the alternate interior angles are congruent, then the lines are parallel. In this case, line \( S \) acts as the transversal cutting lines \( R \) and \( T \). The angles formed are right angles, which are congruent. Therefore, lines \( R \) and \( T \) are parallel to each other. Hence, \( R \parallel T \).
