minus-square@[email protected]linkfedilink20•edit-27 months 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@[email protected]linkfedilink2•7 months 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
minus-square@[email protected]linkfedilink1•7 months agoEspecially if you are bad at this stuff you know that drawing anything like that accurately is a real pain and nobody who can avoid it will ever do it to represent anything accurately. That is what labels are for.
minus-square@[email protected]linkfedilink19•7 months agoNope I’m not saying that. I’m saying this is a gotcha question that demotivates learners.
minus-square@[email protected]linkfedilink10•7 months agoI see. I agree completely. The only place this belongs is as a thought experiment on making assumptions in geometry.
minus-square@[email protected]linkfedilink3•7 months agoThe sum of the angles of a triangle are always 180°
minus-square@[email protected]linkfedilink6•7 months agoYes, I believe I implied this by suggesting that the sum of angles being 190° is absurd.
