Any ideas

paki · Answer

confused with the coordinates....

anonymous · Answer

When I graphed it, it looked like it could be a right triangle but I just don't know for sure

paki · Answer

if you graphed it in a rite way, then it will be true of course....

ganeshie8 · Answer

it is indeed a right triangle, 
you may use pythagoras theorem to prove it

ganeshie8 · Answer

find the lengths of sides :
RS = ?
ST = ?
RT = ?

then check : a^2+b^2 = c^2
