Below represents the proof that the quadrilateral QRST is a parallelogram
<h3>How to prove that QRST is a parallelogram?</h3>
The coordinates are given as:
Q = (-1,-1)
R = (2,9)
S = (-4,5)
T = (-7,-5)
Calculate the length of each side using:
![d = \sqrt{(x_2 -x_1)^2 + (y_2 -y_1)^2}](https://tex.z-dn.net/?f=d%20%3D%20%5Csqrt%7B%28x_2%20-x_1%29%5E2%20%2B%20%28y_2%20-y_1%29%5E2%7D)
So, we have:
![QR = \sqrt{(-1 - 2)^2 + (-1 -9)^2} = \sqrt{109}](https://tex.z-dn.net/?f=QR%20%3D%20%5Csqrt%7B%28-1%20-%202%29%5E2%20%2B%20%28-1%20-9%29%5E2%7D%20%3D%20%5Csqrt%7B109%7D)
![RS = \sqrt{(-4 - 2)^2 + (5 - 9)^2} = \sqrt{52}](https://tex.z-dn.net/?f=RS%20%3D%20%5Csqrt%7B%28-4%20-%202%29%5E2%20%2B%20%285%20-%209%29%5E2%7D%20%3D%20%5Csqrt%7B52%7D)
![ST = \sqrt{(-7 + 4)^2 + (-5 - 5)^2} = \sqrt{109}](https://tex.z-dn.net/?f=ST%20%3D%20%5Csqrt%7B%28-7%20%2B%204%29%5E2%20%2B%20%28-5%20-%205%29%5E2%7D%20%3D%20%5Csqrt%7B109%7D)
![TQ = \sqrt{(-7 + 1)^2 + (-5 + 1)^2} = \sqrt{52}](https://tex.z-dn.net/?f=TQ%20%3D%20%5Csqrt%7B%28-7%20%2B%201%29%5E2%20%2B%20%28-5%20%2B%201%29%5E2%7D%20%3D%20%5Csqrt%7B52%7D)
The above computations show that opposite sides are equal.
Next, we determine the slope of each side using:
![m = \frac{y_2 -y_1}{x_2 -x_1}](https://tex.z-dn.net/?f=m%20%3D%20%5Cfrac%7By_2%20-y_1%7D%7Bx_2%20-x_1%7D)
So, we have:
![QR = \frac{9 + 1}{2 + 3} = \frac{10}3](https://tex.z-dn.net/?f=QR%20%3D%20%5Cfrac%7B9%20%2B%201%7D%7B2%20%2B%203%7D%20%3D%20%5Cfrac%7B10%7D3)
![RS = \frac{5-9}{-4 - 2} = \frac{2}3](https://tex.z-dn.net/?f=RS%20%3D%20%5Cfrac%7B5-9%7D%7B-4%20-%202%7D%20%3D%20%5Cfrac%7B2%7D3)
![ST = \frac{5+5}{-4 + 7} = \frac{10}3](https://tex.z-dn.net/?f=ST%20%3D%20%5Cfrac%7B5%2B5%7D%7B-4%20%2B%207%7D%20%3D%20%5Cfrac%7B10%7D3)
![TQ = \frac{-5+1}{-7 + 1} = \frac{2}3](https://tex.z-dn.net/?f=TQ%20%3D%20%5Cfrac%7B-5%2B1%7D%7B-7%20%2B%201%7D%20%3D%20%5Cfrac%7B2%7D3)
The above computations show that opposite sides are parallel, because they have equal slope
Hence, the quadrilateral QRST is a parallelogram
