OK, I am learning about Parallelograms at the moment and I am stuck on a certain problem....
COORDINATE GEOMETRY Find the coordinates of the intersection of the diagonals of parallelograms PRYZ given each set of vertices.
P(2,5) R(3,3) Y(-2,-3) Z(-3,-1)
Please help me........
I think I have the hang of it. I was using the slope formula instead of the midpoint formula and that got me all twisted around.....
How about things like these...
What about something of this extent....
COORDINATE GEOMETRY Determine whether a figure with the given vertices is a parallelogram. Use the Method INdicated:
P(-5,1) S(-2,2) F(-1,-3) T(2,-2) ; Slope Formula...
Remember that a parallelogram is defined by the fact that it has two pairs of parallel sides. NOW is the time for the slope formula - find the slopes of all four lines. If the slopes of each pair of opposite sides are the same, then you have two sets of parallel sides and, hence, a parallelogram.
I was referring to the question in the post immediately above mine - the original post was answered. The post immediately above mine, as you can see, is about proving that 4 given points are vertices of a parallelogram using the slope method.
Thanks for the snark, though.
