If anyone has any tips please let me know
If we call the vertices A,B,C and the opposite sides a,b,c then we have
(A): a=3, b=4, c=5
(B): a=6, b=√85 stop right there
(C): a=13, b=10√2 stop right there
(D): a=8, b=10, c=6
we have a winner!
(A): a=3, b=4, c=5
(B): a=6, b=√85 stop right there
(C): a=13, b=10√2 stop right there
(D): a=8, b=10, c=6
we have a winner!
D - thank you so much - that's the one I marked but needed to be sure.
Can someone explain to me how you got those values from the (x,y) values ???? help? I want to learn how to do it for myself and my teacher didn't include this part in the lesson. :(((
