Project My Angle by nuhman10


									My Angle

In this project you will calculate your own angle and make three other angles that combine
together in different ways to create 90 and 180 angles. After that you will look at patterns
you observe about the angles and how they fit together.

           Any two angles whose measures add up to 180 are supplementary angles.
           (We call them perfect mates).
           Any two angles whose measures add up to 90 are complementary angles.
           (We call them best friends or compadres).

Calculate your angle by adding your birth year, your birth month and your birth day. Mine is
60 + 12+ 29 =101
Angle 1: Construct your angle out of colored paper.
Angle 2: Construct your angle's supplement (perfect mate)
Angle 3: Construct the complement to Angle 2 (best friend)
Angle 4: Construct the supplement to Angle 3 (the perfect mate)

Write   an illustrated report
        Explain your angles and how you calculated them
        Classify them as acute or obtuse
        Explain any patterns you see.
        What happens when you put them all together?

We are practicing constructing angles with a protractor, and calculating supplementary and
complementary angles. This is also the first written project you have done in this class, so
you are learning what I expect in written reports.
