amistre, wth?

hero · Answer

What kind of method is that?

anonymous · Answer

Thank ya'll so much! I couldn't figure it out

hero · Answer

Explain in more detail please

amistre64 · Answer

well, C-A is distance and direction to midpoint, added to the midpoint C is your end point

amistre64 · Answer

hence:

C+(C-A) = other end

hero · Answer

Is that the best explanation you have?

amistre64 · Answer

yep.  distance from A to C added to C

hero · Answer

You're not good with the whole "general explanation" thing are you?

amistre64 · Answer

not really, i need a better thesaurus :)

hero · Answer
