Question
Identify the line perpendicular to AB.
- r
- s
- t
- u
Hint:
From the figure it is clearly evident that the angle between AB and s is 90 degrees. All other angles are either greater than or lesser than 90 degrees.
The correct answer is: s
s is the line perpendicular to AB.
Lines are perpendicular when the angle between them is 90 degrees.

What are the lines parallel to CD?
For such questions, we should know about parallel lines and perpendicular lines. The line joining the two parallel lines will be perpendicular to both the lines. So, the other way to check for parallel lines is by drawing a line joining both.

Use the Vertical Angles Congruence Theorem to find the measure of each angle in the diagram at the right.
For such questions, we should know properties of vertical angles. We should know the rules of algebra to solve the equations. The alternate way to solve the question will be using supplementary angles. When two angles intersect, the sum of adjacent angles is 180°.
