Step-by-step explanation:
let vertex A(-3,-4) ,B(7,2) , C (12,5)
distance between AB= √(7+3)^2+(2+4)^2
AB= √100+36
AB=√136unit
BC= √(12-7)^2+(5-2)^2
BC=√25+9
BC=√34unit
AC= √(12+3)^2+(5+4)^2
AC= √225+81
AC= √306
hence AB is not equal to BC
BC is not equal to AC
AC is not equal to AB
hince ABC are collinear point
