Perpendicular lines.
A perpendicular line is a type of intersecting line that crosses the other line at a right angle.
Two intersecting rays.
They can but don't have to as long as they are intersecting it doesn't matter whatt type of angles they form. * * * * * NO! The fact that they are perpendicular means that they intersect at right angles. Not an acute angle, not an obtuse angle but a right angle. That is what perpendicular is.

perpendicular lines are a special type of intersecting line that happen to intersect at 90 degree angles
Right angles are formed by perpendicular lines. If the lines would extend, to make two intersecting lines, they would form four right angles. Perpendicular lines are written like this: . From its shape, you can already tell that it forms at least two right angles.
Opposite angles.
