The intersecting lines that form a right angle are defined as perpendicular lines option (D) is correct.
What is a perpendicular line?
Lines that intersect at a right angle are named perpendicular lines. Lines that are always the same distance apart from each other are known as parallel lines.
As we know, in the right-angle triangle one angle is 90 degrees.
And perpendicular lines where they intersect make a right-angle or 90 degrees angle.
So, Intersecting lines that form a right angle are defined as perpendicular lines.
Thus, the intersecting lines that form a right angle are defined as perpendicular lines option (D) is correct.
