How does using coordinate geometry help you determine what type of quadrilateral you are looking at?
explain your question further. . .
that's all there is to the question.
Then simply plot the four coordinates and simply see what the shape is, if you can recognize it visually when you draw lines between the points (going around). |dw:1342707434655:dw|
For example, what is the geometric figure from the 4 points above when I connected the dots?
a trapezoid
There are also different properties to quadrilaterals (rhombus, parallelogram, square, trapezoid, etc.) that have various characteristics which I am sure you have studied. Using the coordinates of these shapes will allow you to easily calculate whether two sides are the same, parallel (same slope), form right angles, etc.
gj @Relientkluver that is correct :-)
