Incomplete question. I inferred you want to know the properties of parallel and perpendicular lines. Which I provided below.
Step-by-step explanation:
In geometry, parallel lines are two lines that are always drawn at the same distance apart and never touch each other. Parallel lines are usually denoted by the symbol ∥.
Here are some of their properties;
When a transversal intersects two parallel lines:
- usually, the corresponding angles of the lines are equal.
- vertically opposite angles are equal.
- the alternate exterior angles are equal.
Perpendicular lines are two lines that meet at a right angle (90 degrees) to each other.
Properties: two lines that meet, implies all four angles are right angles.
