a quadrilateral where each angle is a right angle
Two lines that form a right angle at their point of intersection is called perpendicular lines.
Perpendicular lines form right angles at their intersections.
perpendicular lines
They are said to be perpendicular lines.
Perpendicular lines intersect and form a right angle. The lines on a square are perpendicular to each line that it touches.
Perpendicular lines intersect to form right angles
Perpendicular lines form right angles at their intersections.
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.
