minus-squareTheOakTree@lemm.eelinkfedilinkarrow-up0arrow-down1·edit-220 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-squareMaggoty@lemmy.worldlinkfedilinkarrow-up3arrow-down1·20 hours agoNope I’m not saying that. I’m saying this is a gotcha question that demotivates learners.
minus-squareTheOakTree@lemm.eelinkfedilinkarrow-up0arrow-down1·20 hours agoI see. I agree completely. The only place this belongs is as a thought experiment on making assumptions in geometry.
minus-squareNoMoreLurkingToo@startrek.websitelinkfedilinkarrow-up0·20 hours agoThe sum of the angles of a triangle are always 180°
minus-squareTheOakTree@lemm.eelinkfedilinkarrow-up0arrow-down1·20 hours agoYes, I believe I implied this by suggesting that the sum of angles being 190° is absurd.
