Plot
and label each point on the coordinate system below: A(2, 3); B(4, 7); C(12, 8); D(10, 4).
Connect A to B, B to C, C to D, and D to A to form a quadrilateral. What type of
quadrilateral does this appear to be?
m = ( y2 - y1 ) /( x2 - x1 ) to find the slope of each segment. |

Do the results
confirm your answer to question 1? Explain why or why not.
Plot and label
each point on the following coordinate system: A(1, 3); B(4, 7); C(9, 7); D(6, 3). Connect
the points in the same order as in the first drawing. What type of quadrilateral does this
appear to be?
to find the length of each segment.

Draw the
diagonals ABCD. Use the slope formula to find the slope of each
diagonal.
What do you think is true about the diagonals of this quadrilateral?
On
a seperate sheet of graph paper, plot and label each point: A (3, 2); B (2, 5); C (8, 7);
D (9,4). Draw the quadrilateral that is formed. Draw the diagonals. What type of
quadrilateral does this appear to be?
Use the slope and distance formulas to find information about the sides and diagonals of
the quadrilateral created in number 9.
What can you now conclude about the type of quadrilateral that ABCD is?
