First Blog Assignment-Get Creative

Welcome to the 416 blog! Now that you have all created gmail account and have been formally invited to be an author on your class blog we can get going.

So far we have learned 5 theorems relating to congruent angles. You will need to know these well and have them at your disposal to proven others concepts in geometry.

Your first assignment is to correctly state each theorem and follow it with a diagram which demonstrates the concept.

You have many tools at your disposal and one of the most useful is Grab which you learned last class. If you have forgotten how to use it, click on the link on the right side to see instructions.

For drawing you may use whatever you like. I am going to show you the smartboard notebook today....which I think you'll have some fun with.

Oh....a reminder....this blog is public which means the whole world can see.....so WOW them.

Here is an example of the first theorem......you can jazz yours up a bit. I used word for this one.
Theorem:Vertically Opposite Angles are congruent. (VOA)





<1 and <4 are ongruent
<3 and <2 are congruent





The theorems you need to show a diagram for are:
Vertically Opposite Angles
Corresponding Angles
Alternate Interior Angles
Alternate Exterior Angles
Co-Interior Angles
Complementary Angles
Supplementary Angles
Sum of Angles on a triangle=180 degrees
In a 30, 60 90 degree triangle, the side opposite the 30 degree angle is 1/2 the hypotenuse.

Have fun!
