Perpendicular lines are any two lines that intersect at a 90 degree angle.
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.

a right angle
Angle
When lines intersect, angle formed between them is Θ or 180-Θ.
No; four angles are formed.
A perpendicular line is formed when two lines meet at a right angle. Opposite angles in a perpendicular line are parallel to each other.
Lines that intersect at right angles.
Angle. Also, two lines which intersect at a point can define a plane.
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.
Coordinateplain
When two lines intersect to form a 90o angle, they are said to be perpendicular.
