Question

If two lines AB and PQ are parallel the ___ of tangent a vector

Answer 1

In elementary geometry, the property of being perpendicular (perpendicularity) is the relationship between two lines which meet at a right angle (90 degrees). The property extends to other related geometric objects. A line is said to be perpendicular to another line if the two lines intersect at a ... means line segment AB is perpendicular to line segment CD.
