(5 ,8) ,(2- ,2) ,(6 ,7ع)(1)
(2) (3, -5), (4, 3), (11, -4)
(3) (4, 7), 8, 4), (7, 11)​

Answer 1

$\bf \huge \: answer : \\ \\ formula \: \: used \\ \\ \: \sf \huge \: c = \frac{x_1 + x_2 + x_3}{3}, \frac{y_1 +y_2 + y_3}{3} \\ \\ 1)(6 ,7) ,(2- ,2) ,(5 ,8) \\ \\ x_1 = 6 \\ x_2 = 2 \\ x_3 = 5 \\ y_1 = 7 \\ y_2 = - 2 \\ y_3 = 8 \\ \\ c = \frac{6 + 2 + 5}{3} , \frac{7 - 2 + 8}{3} \\ \\ c = \frac{13}{3} , \frac{13}{3}$
