Rays, I believe.
a right angle

A perpendicular line is formed when two lines meet at a right angle. Opposite angles in a perpendicular line are parallel to each other.
an angle
Lines that intersect at right angles.
A perpendicular line is formed when two lines intersect and form a 90 degree, or right, angle.
When two lines intersect to form a right angle they are called perpendicular.

Perpendicular lines intersect each other at right angles.
Perpendicular lines intersect each other at right angles
No; four angles are formed.
It could be the horizontal x and the vertical y axes that intersect each other at right angles on the Cartesian plane at the point of origin which is (0, 0)
