Perpendicular.
Perpendicular lines are, by definition, lines which are at right angles to another line. In other words in a capital letter T the vertical line is perpendicular to the horizontal one because they are at right angles (90 degees) to one another.
Perpendicular lines meet at right angles
They do not meet at right angles to one another.
Lines that intersect right angles (ninety-degree angles) are described as perpendicular.
If two lines intersect at right angles then they are perpendicular!

All of them. If its truly intersecting lines, they have to form right angles. All of them. If its truly intersecting lines, they have to form right angles.
Perpendicular lines form right angles when they intersect.
two lines that are perpendicular form right angles
Lines that intersect right angles (ninety-degree angles) are described as perpendicular.
A square has four right angles. A right angle is an angle of 90 degrees. Right angles have two lines that are perpendicular to one another.
If two lines intersect each other at right angles, that means that the measure of each angle between the two lines is 90o. Another way of stating this is to say that two lines are perpendicular.
Perpendicular lines intersect to form right angles
Perpendicular lines form right angles at their intersections.
If two lines intersect at right angles then they are perpendicular!
