their slopes are negative reciprocals of each other. and they make a right angle when they intersect.

By definition, any lines/segments that are perpendicular to each other either do, or (in the case of non-intersecting segments) would, intersect each other at right angles. A right angle being a 90* angle. Therefore, perpendicular, intersecting line segments will form 4 90* angles.
A pair of perpendicular line segments is not shown among the pictures you've submitted.
The following is the answer.
How am i supposed to kow this??? I am in second grade!
The segments of a square are perpendicular. Take the letter " T " for example. Where the bottom line connects the the top line forms a 90 degree angle, which makes them two lines perpendicular.
