When it comes to identifying perpendicular lines, it's crucial to know that these lines cross at a right angle (90 degrees). On a two-dimensional plane, a line's slope will be the negative reciprocal of its perpendicular line's slope. This means that if we have a line A with a slope m, then a line that is perpendicular to A will have a slope of -1/m.
