Which shape does NOT have perpendicular

perpendicular lines? Mark your answer.

Riangles have perpendicular sides, rectangles have both perpendicular and parallel sides, but other quadrilaterals might not.

Perpendicular lines are lines that cross one another at a 90° angle. They have slopes that are opposite reciprocals of one another. Unlike parallel lines that never touch, perpendicular lines must intersect.

Therefore, the shape with 2 lines that don't intersect/touch each other, is the shape that does not have perpendicular lines.
