If two lines intersect at right angles then they are perpendicular!
Lines that intersect right angles (ninety-degree angles) are described as perpendicular.
Coordinate Plane
Acute, obtuse, or 90 degree (right) angles.

Perpendicular lines form right angles when they intersect.
Perpendicular lines intersect to form right angles
If two lines intersect at right angles then they are perpendicular!
Lines that intersect right angles (ninety-degree angles) are described as perpendicular.

yes, it makes four right angles.
Only if the angles formed are right angles otherwise they form vertical opposite equal angles
Perpendicular lines intersect at right angles.
