Their are Perpendicular.
No.
Perpendicular lines are any two lines that intersect at a 90 degree angle.
a coordinate plane
Not necessarily. Consider two lines that intersect at some angle other than 90 degrees. Then the angle of intersection is not 90 degrees means they are not perpendicular. But, because they intersect, neither are they parallel.

Lines that intersect at right angles.
When lines intersect, angle formed between them is Θ or 180-Θ.
When two lines intersect to form a 90o angle, they are said to be perpendicular.
The lines are perpendicular.
When two lines intersect to form a right angle they are called perpendicular.
Angles are formed when two lines intersect (depends on the way the lines intersect to determine what kind of angles they are). Since parallel lines do not intersect each other at all, there is no angle between them.
Perpendicular lines intersect each other at right angles
No. Lines can intersect at any possible angle.
