Answer 1

Given points;

• A(1,-1)
• B(4,-1)
• C(4,3)

Thus by using midpoint formula ( x = x1+x2/2)(y = y+y2/2)

midpoint of AB;

x = 1 + 4 / 2

x = 5/2

x = 2.5

y = -1 -1 / 2

y = -2/2

y = -1

midpoint of BC;

x = 4+4/2

x=4

y = -1+3/2

y= 2/2

y = 1

midpoint of CA;

x = 4+1/2

x = 5/2

x = 2.5

y =3 - 1/2

y= 2/2

y = 1

Thus midpoint of

AB (2.5,-1)

BC(4,1)

CA,(2.5,1)
