Line CF bisect segment ST. All lines bisect a segment at a 90 degree angle, so line CF and segment ST are perpendicular.
Why or why not is this argument valid?

Best ResponseYou've already chosen the best response.0so.. CF bisects ST are they perpendicular lines?

Best ResponseYou've already chosen the best response.0If they weren't they would never bisect.

Best ResponseYou've already chosen the best response.0hmmm was checking the bisect meaning, and it's just to divide in half but I'd say yes, assuming "ll lines bisect a segment at a 90 degree angle"

Best ResponseYou've already chosen the best response.0So would the answer be "since CF and ST collide they would have to be perpendicular"?

Best ResponseYou've already chosen the best response.0if you move around the blue line, the red bisector, can bisect without being perpendicular

Best ResponseYou've already chosen the best response.0Meaning when they're perpendicular but right on top of eachother.... so a better answer would be since all lines bisect at 90 degrees and CF bisects ST they would have to be perpendicular correct?

Best ResponseYou've already chosen the best response.0hmmm well, if we assume " All lines bisect a segment at a 90 degree angle" is true then CF and ST are obviously perpendicular but you can bisect another line, that is, cut it two equal sides WITHOUT being perpendicular so " All lines bisect a segment at a 90 degree angle" is a fishy statement
