When two lines intersect to form a right angle they are called perpendicular.
A right angle
The lines that intersect to Form A right triangle are called Perpendicular Lines; the resulting meeting point of these two lines is called the vertex of the angle.
If lines intersect they CANNOT BE PARALLEL. Speak to your teacher!
Perpendicular lines intersect at a 90 degree angle. Parallel lines do not intersect, nor would they ever intersect if continued infinitely.
These lines are called perpendicular lines.
Perpendicular
Skew lines are non-coplanar, which means they are in different planes. Skew lines are in different planes and they do not intersect.
When two lines intersect to form a right angle they are called perpendicular.
perpendicular lines
Lines that intersect at right angles.
perpendicular
When two lines intersect then the degree is called an angle. This does not work with parallel lines.
Lines that intersect but do not form a right are just called intersecting lines. Perpendicular lines DO form a right angle when they intersect.
Such lines are called perpendicular.
