Answer 1

Answer: are perpendicular

Explanation:

Two lines intersecting at a right angle are said to be perpendicular. When the lines cross each other, we say the lines have intersected.

The point of intersection of the lines is the pointe where they cross one another. In case the lines never interesct, such lines are refered to as the parallel lines.
