Question

Two lines intersecting at a right angle

form a line.
are parallel.
are perpendicular.
form a ray.

Answer 1

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.

Answer 2

Answer:

Perpendicular lines

Step-by-step explanation:

Two or more lines are called intersecting lines.That point would be on each of these lines.
