two lines intersecting at a right angle\nform a line.\nare parallel.\nare perpendicular.\nform a ray.
Answer
Brief Explanations:
By definition, two lines that intersect at a right - angle (90 degrees) are perpendicular. Parallel lines never intersect, and forming a line or a ray is not the correct description for two lines intersecting at a right - angle.
Answer:
are perpendicular.
