Two lines intersecting at a right angle
Vaselesa [24]

Answer: THIRD OPTION

Step-by-step explanation:

We need to remember that a right angle is an angle that measures 90 degrees.

By definition, when two or more lines intersect (or cross one another ) at a 90-degree angle, then these lines are called "Perpendicular".

Therefore, in this case, we know that these two lines intersects at a right angle (angle of 90 degrees), then, we can conclude that these lines are Perpendicular.

This matches with the third option.
