To determine if two line segments are perpendicular, you need to check the relationship between their slopes. If the slopes of two line segments are negative reciprocals of each other, then the lines are perpendicular.
For example, if the slope of the first segment is ‘m1’ and the slope of the second segment is ‘m2’, the condition for the lines to be perpendicular is: m1 * m2 = -1. This means that if one slope is 2, the other must be -1/2.
Another way to verify if two line segments are perpendicular is to look at their graphical representation. If the angle formed between them is a right angle (90 degrees), then the segments are perpendicular.
In summary, you can check the slopes mathematically or verify graphically to confirm if the line segments intersect at a right angle.
