Term Project due Friday, 14/10/11

So folks, you've obviously been burning the midnight oil on your term projects. For those of you who got an incorrect equation for the perpendicular line in your Part I of the project, the correct equation (which is also obvious from the diagram) is:

              y = 3x - 4


Knowing the correct equation will be very helpful for part (d) i) in your Term Project Part II.

Now, before I give any hints and, surely, you will not need any hints for most of the project except for part (d) ii), I want you to post questions that you may have and that way I can post hints accordingly.

For now I will give you the following leads:

• Note that AM and MB are equal segments since M is the midpoint of AB.
• If you take any point on the perpendicular line you will see that it forms two triangles, one with points M and B and the other with points M and A. Pay attention to what kind of triangles are formed.
• Simran had suggested a great alternative idea in class for checking if lines are perpendicular or not. The method she used can also be used to prove the equidistance of any point on the perpendicular from the end points of the segment. 
• Remember that you have learned about congruent figures!
