Triangle ABC has vertices located at A(6, 8), B(3, 2), and C(3, 8) on the coordinate grid.

Which equation could be used to show that a2+b2=c2?

(8−2)2+(6−3)2=((8−2)2+(6−3)2−−−−−−− −−−−−−−−√)2

(8−2)2+(6−3)2=(8−2)2+(6−3)2−−−−−−−− −−−−−−−√

(8−2)+(6−3)=((8−2)2+(6−3)2−−−−−−−−− −−−−−−√)2

(8−2)+(6−3)=(8−2)2+(6−3)2−−−−−−−−−− −−−−−√
