Let

P=(P_x,P_y),\quad Q=(Q_x,Q_y)

If M is the midpoint, the x and y coordinates of M are the average of the x and y coordinates of P and Q:

M=\left(\dfrac{P_x+Q_x}{2},\ \dfrac{P_y+Q_y}{2}\right)

We can solve this expression for the coordinates of Q:

M_x = \dfrac{P_x+Q_x}{2} \implies Q_x = 2M_x-P_x

M_y = \dfrac{P_y+Q_y}{2} \implies Q_y = 2M_y-P_y

Plug in the values for the coordinates of M and P to get

Q_x = 2M_x-P_x = 2\cdot 5-11 = 10-11=-1

Q_y = 2M_y-P_y = 2\cdot (-2) - (-10) = -4+10=6

Find the value of x and y in the parallelogram. Explain.
Ray Of Light [21]

x = 26


Because 26-2=24 which would be right because it needs to equal the same size as the other side that is across from it.


y = 11


Because it’s the same size as the bottom side, which is also the side across from it.



This is true because a parallelogram has 2 sets of parallel side!!!



I hope this helps! :)
