These web-based activities were developed, during summer sessions from 1997 through 1999, by students at Mainland High School, located in Daytona Beach, FL. As part of Mainland's CCTT grant, the students were given permission by the book's publisher to convert the ancillary materials of the County's adopted Algebra 1 Textbook (Glencoe Algebra 1 - ISBN: 9780028253282) into html format.
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.

Do the results confirm your
answer to question 4? Explain why or why not.__________
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 separate 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. Show your work on your graph paper.
What can you now conclude about the type of quadrilateral that ABCD is? __________
