Question

Which shape does NOT have perpendicular
perpendicular lines? Mark your answer.​

Answer 1

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.

Answer 2

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