perpendicular lines
a quadrilateral where each angle is a right angle
A right angle.
a coordinate plane
They are said to be perpendicular lines.
Perpendicular Lines form right angles at their point of intersection
Lines that intersect to form right angles at their point of intersection have slopes that are negative reciprocals.

These are called perpendicular lines.
The lines are called perpendicular lines.
Two perpendicular lines form right angles at their point of intersection.
It matters about how the lines intersect. If they intersect like this: +, then the point of intersection is called a perpendicular intersection. If the corners do not have right angles and the angles are obtuse and acute, then it is called intersecting lines. Glad to help!almost.
