A rectangle has vertices whose coordinates are A(1, 4), B(4, -1), C(-1, -4), and D(-4, 1). Find the coordinates of the midpoints of each side. (Enter answers as improper fractions.) Midpoint of AB = ( , ) Midpoint of BC = ( , ) Midpoint of CD = ( , ) Midpoint of AD = ( , )

OpenStudy (anonymous):

please help!

OpenStudy (anonymous):

mipdpoint between any two point (a , b) and (c, d) is ((a+b)/2 , (b+d)/2)

OpenStudy (anonymous):

for example, for points A and B, (1+4)/2 is your x coordinate of the midpoint (4+(-1))/2 is your y coordinate of the midpoint so simplified, (5/2, 3/2) is your midpoint for AB can you do the rest? i can verify your answers if you want.

OpenStudy (anonymous):

omg thanks yes! thanks for clarifying it! and yes please verify my answers, id love that!:)

OpenStudy (anonymous):

Midpoint of BC = 3/2 , 5/2 ?

OpenStudy (anonymous):

is it right?

OpenStudy (anonymous):

that should be -5/2 right?

OpenStudy (anonymous):

oh yes:)

OpenStudy (anonymous):

and how about

OpenStudy (anonymous):

then correct... :)

OpenStudy (anonymous):

Midpoint of CD = -5,2 , -3/2

OpenStudy (anonymous):

yes... :)

OpenStudy (anonymous):

and finally Midpoint of AD = 5/2 -3/2

OpenStudy (anonymous):

x first, then y.... -3/2, 5/2

OpenStudy (anonymous):

oh okkk:)

OpenStudy (anonymous):

good work seashell .. :)

OpenStudy (anonymous):

thanks to you!:)appreciate it

OpenStudy (anonymous):

yw...:)
