Question

Determine whether the given coordinates are the vertices of a triangle. Explain. L(–24, –19), M(–22 ,20), N(–5, –7) a. yes: LM + MN > LN, LM + LN > MN, LN + MN > LM c. no: LM + MN < LN b. no: LM + MN = LN d. yes: LM + MN < LN, LM + LN < MN, LN + MN < LM

use the distance formula to work out the distance between each coordinate.

sry cant do it now, but happy to do it later (if no one has done so). let me know! :)

anonymous · Answer

alright ill wait when you can (: its cause this distance stuff is too confusing ;P @marigirl
