false ... perpendicular means at 90 degrees. therefore it is not possible
No, the slope will be -1
No. Perpendicular lines for right angles. That is why they are called perpendicular.
Non-perpendicular intersecting lines. There is no special name.
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).

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. !!!!!
No, that is not true.
True.
Two lines are perpendicular if they cross at 90 degree angles.
