Given quadrilateral RSTU, determine if each pair of sides (if any) are parallel and which are perpendicular for the coordinates
nika2105 [10]
We would need to figure out the gradient of each "pair", as provided in the image.

The equation of the gradient is found by,

m = \frac{ y_{2 } - y_{1 } }{ x_{2 } - x_{1 } }

Parallel lines mean they have the same gradient
Perpendicular lines will follow the formula m_{1 } *  m_{2 } = -1
"None" will apply to those that do not follow either.

Now we calculate the gradient of the pairs given to us by substituting the x and y values.

RS = \frac{2-5}{8-(-1) }
      = -\frac{1}{3}

TU = \frac{-2 - 5}{-4 -5}
      = \frac{7}{9}

Therefore, the "pair" RS and TU will be NONE.

ST = \frac{5 - 2}{5-8}
     = -1

RU = \frac{-2 -5}{-4 -(-1) }
      = \frac{7}{3}

Therefore, the "pair" ST and RU is also NONE.

Hope this helped! Feel free to ask me if there's any part of the working you don't understand :)

xeze [42]

This is a guess, but, from what I've researched, maybe decrease? I've looked into it alot and that's just I think, though, it may depend on the previous height. Still, just an educated guess (I've got 100% on all kinds of quizzes because of educated guesses so, it may work!)
