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."
What is a 'Straight Angle'???? Perpendicular lines meet at 90 degrees ( right- angles).
They are perpendicular lines
Perpendicular lines intersect to form right angles
Perpendicular lines form right angles at their intersections.
By definition, perpendicular lines form right angles.
Perpendicular lines form 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."
If two lines intersect at right angles then they are perpendicular!
What is a 'Straight Angle'???? Perpendicular lines meet at 90 degrees ( right- angles).
two lines that are perpendicular form right angles
yes, perpendicular lines form four right angles its be cuz two lines are intersects
These are called perpendicular lines.
Perpendicular lines intersect to form right angles.
Perpendicular lines form right angles when they intersect.
Perpendicular.
