Lines, angles, shapes and symmetry
Sort pairs of lines by whether they are parallel, perpendicular or neither.
Sort
Are the two lines parallel, perpendicular, or neither?
Tap a card, then tap its group.
Assumptions
•
Parallel lines go the same way and never meet, like railroad tracks.
•
Perpendicular lines meet at a right angle, like the corner of a page.
•
Lines that meet at any other angle are neither.
