Fixed pencil of parallel lines

WebMar 7, 2024 · Pencil of lines In a plane, let u and v be two distinct intersecting lines. For concreteness, suppose that u has the equation, aX + bY + c = 0 and v has the equation … WebWe would say these two lines are perpendicular if they intersect at a right angle. So they clearly intersect. In order for them to intersect at a right angle, the angle formed between these two lines needs to be 90 degrees. And if any one of these angles is 90 degrees, the rest of them are going to be 90 degrees.
