perpendicular lines run at 90% angles to each other not Parallel
No, the slope will be -1
True
If the lines are perpendicular, their slopes are negative reciprocals.If the lines are perpendicular, their slopes are negative reciprocals.If the lines are perpendicular, their slopes are negative reciprocals.If the lines are perpendicular, their slopes are negative reciprocals.
False. Every rhombus is a parallelogram, but not every rhombus is a square. Only those that have right angles are squares. Every rhombus is a parallelogram because its diagonal lines are perpendicular, and they bisect an interior angle.
TRUE:: The first two lines lie in the same plain, but are perpendicular to each other. The third line passes through the plane of the first two lines so it is also perpendicular. Think 3-dimension. !!!!!
Parallel lines are never perpendicular. Perpendicular lines are co-planar and cross at right angles.
What is a 'Straight Angle'???? Perpendicular lines meet at 90 degrees ( right- angles).
