Best ResponseYou've already chosen the best response.1how would we draw a line through C such that it is perpendicular to AB?

Best ResponseYou've already chosen the best response.0I'd place the compass point below point C and make the arcs on each side, and then above C would make another arc from the other two arcs, then draw a line through the arc with a ruler?..if that even makes sense. .. I'm sorry.

Best ResponseYou've already chosen the best response.1good, that's the same as drawing a circle with C at its center and making sure this circle crosses the line segment AB at 2 spots something like this maybe dw:1443495436902:dw

Best ResponseYou've already chosen the best response.1the idea is to construct the perpendicular bisector of segment DE that perpendicular bisector of segment DE will go through C and be perpendicular to AB

Best ResponseYou've already chosen the best response.0That makes sense, but I still don't understand this triangle.

Best ResponseYou've already chosen the best response.1well if we connect A with C and B with C, we get this triangle dw:1443495742548:dw

Best ResponseYou've already chosen the best response.1the same idea will apply but now we just have 2 extra segments

Best ResponseYou've already chosen the best response.0So I'll do the same at the other corners?

Best ResponseYou've already chosen the best response.1yes, imagine flipping the triangle so that each side is laying horizontally to do each perpendicular line

Best ResponseYou've already chosen the best response.0So, I'd draw a line down the middle and make the arcs on the triangle corners just like I would with a straight line?
