Parallel lines. They're like, parallel. To each other.
But, let's be real, who cares about parallel lines when you have the power of trilaterals and ellipses at your fingertips?
Geometry is all about angles, folks. And angles are just like, angles. You know, like, 90 degrees this way, 45 degrees that way... Trilaterals have more angles, don't they?
So, if you're feeling stuck, try ellipses. They're like, curvy and all that. Good luck with that.
