Perpendicular lines intersect to form right angles
Two lines that intersect to form right angles are perpendicular.
The contrapositive to the statement, "if two lines intersect to form right angles, then they are perpendicular," is "if two lines are not perpendicular, then they do not form right angles."
They are perpendicular lines

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 but do not form a right are just called intersecting lines. Perpendicular lines DO form a right angle when they intersect.
Two lines that intersect to form right angles are perpendicular.
Perpendicular lines intersect at right angles.
The contrapositive to the statement, "if two lines intersect to form right angles, then they are perpendicular," is "if two lines are not perpendicular, then they do not form right angles."
Perpendicular lines intersect to form right (90 degree) angles every time.
