sides of a right angle
To check if two rays are perpendicular, you can examine the angle formed between them. If the angle measures exactly 90 degrees, the rays are perpendicular. Alternatively, if you have the slopes of the rays (assuming they are represented as lines in a coordinate system), you can multiply the slopes together; if the product is -1, the rays are perpendicular.
