minus-square@TheOakTree@lemm.eelinkfedilink13•edit-216 hours ago…what? I get that this drawing is very dysfunctional, but are you going to argue that a triangle within a plane can have a sum of angles of 190°?
minus-square@Maggoty@lemmy.worldlinkfedilink14•16 hours agoNope I’m not saying that. I’m saying this is a gotcha question that demotivates learners.
minus-square@TheOakTree@lemm.eelinkfedilink7•16 hours agoI see. I agree completely. The only place this belongs is as a thought experiment on making assumptions in geometry.
minus-square@NoMoreLurkingToo@startrek.websitelinkfedilink1•16 hours agoThe sum of the angles of a triangle are always 180°
minus-square@TheOakTree@lemm.eelinkfedilink3•16 hours agoYes, I believe I implied this by suggesting that the sum of angles being 190° is absurd.
minus-square@starman2112@sh.itjust.workslinkfedilink1•16 hours agoNo, they’re saying that unless you’re already good at this stuff, it’s easy to assume that a visually 90° angle is actually 90° even when it’s not
