A line is perpendicular if it meets at 90o.
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."
right angles
Perpendicular lines intersect to form right angles
Perpendicular lines form right angles at their intersections.
They are perpendicular lines
By definition, perpendicular lines form right angles.
If two lines intersect at right angles then they 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."
Perpendicular lines form right angles
two lines that are perpendicular form right angles
right angles
Perpendicular lines form right angles when they intersect.
yes, perpendicular lines form four right angles its be cuz two lines are intersects
