Answer:
Parallel lines: AB and CD Perpendicular lines: EF and CD Neither parallel nor perpendicular: GH and EF
Step-by-step explanation:
In the given figure, some titles like parallel lines, perpendicular lines and neither parallel nor perpendicular lines are given. we have to match these titles with correct option.
Here, ∠AOF=∠COF=90°
Corresponding angles that are ∠AOF and ∠CO'F are equal. Hence the lines making these angles are parallel.
⇒ Lines AB and CD are parallel.
Now perpendicular lines, those lines which makes 90° angles with each other. In the given figure, lines AB and CD makes 90° angle with line EF.
Hence, the option which is given is EF and CD.
Neither parallel nor perpendicular, the lines which does not makes 90° angle and not 0° with each other are neither parallel nor perpendicular. Hence, the correct match will be GH and EF.
∴ Parallel lines: AB and CD
Perpendicular lines: EF and CD
Neither parallel nor perpendicular: GH and EF
