Help with coordinate geometry - Core 1

Aha, I've been revising for a while.. but I just came across a question..

In coordinate geometry, i've been given 4 coordinates. Asked to draw it and show, by calculation, that it is a trapezium. Similar questions say show, by calculation, that it is a parallelogram etc.

Anyone know how I can do this? Thanks for the help!

Could you give me the coordinates?
But first start by drawing it out. Use (y2-y1)/(x2-x1) to find the gradient of the parallel lines show that it's equal.
