You drawing your own lines now, are you? Come on don't be a sore loser. Perpendicular lines cross at right angles. That's why they're not used in running races.

Aug 15, 2016 · In track, this means making sure runners cover the same distance. Short distances make this easy---simply paint a perpendicular line across the track to denote the starting and finishing...

In summary: the longitude lines are all "parallel" straight lines on the sphere (as in they are geodesics perpendicular to the same geodesic (the equator)). The latitude lines are not even lines and not parallel lines in any meaningful way.
Jun 9, 2014 · However, I couldn't find a clear way to explain why those lines are perpendicular iff $a_k \times a_{\ell}= -1$. Of course, it's obvious if we use the fact that $a = \tan (\alpha)$ with $\alpha$ being the angle at which line intersects the X axis and that $\tan (\alpha) = - \cot (\frac{\pi}{2} + \alpha)$.
Writing equations of perpendicular lines (example 2) Write equations of parallel & perpendicular lines. Proof: parallel lines have the same slope. Proof: perpendicular lines have opposite reciprocal slopes. Analytic geometry FAQ.

Oct 10, 2023 · Perpendicular lines are two straight lines that meet or intersect at 90°. The opposite of perpendicular lines are parallel lines. Unlike perpendicular lines, parallel lines never intersect. The equation of a line that is perpendicular is y = mx + c.
