[–] PP_BOY_@lemmy.world 19 points 1 year ago (2 children) Learned this one in 6th grade geometry: drawing a square in thr corner doesn't make it 90° permalink fedilink source hideshow 4 child comments replies: [–] Mr_Fish@lemmy.world 12 points 1 year ago But these are all right angles, as long as the two arcs are centered on the same point as the intersection of the two straight lines. permalink fedilink source parent [–] Zagorath@aussie.zone 4 points 1 year ago drawing a square in thr corner doesn’t make it 90° No, it doesn't, but it does mean that, for the purposes of your 6th grade geometry question, you can assume the angle is a right angle. Even if it visible looks like 45°, if they put a square there, that's 90. More to the point though, a radius of a circle always meets the circumference at 90 degrees. All the squares in this problem are doing is telling you "this line, if it were continued, would be the radius of the incomplete circle". permalink fedilink source parent
