What is a Coordinate Geometry
When developing a coordinate geometry proof
- draw and label the graph
- state the formulas you will be using
- show ALL work (if you are using your graphing
part of your work.)
- have a concluding sentence stating
Read the question carefully. The wordtrapezoid, by definition, tells you that you are looking for a figure with ONLY ONE set of parallel sides. Lines are parallel when they have the sameslope. You will use the Slope Formula.
Draw a neat, labeled graph for the problem.State the formula that you will be using.
Show ALL work!! We are looking for ONE set of parallel sides AND one set on non-parallel sides.
Be sure to state the connection between the slopes and the sides being parallel or non-parallel.
End with a concluding sentence stating WHY you know the figure is a trapezoid.
