Reference Angles and Special Right Triangles/dilation.
1. Find the reference angles for the quiz problems
2. Find the reference angles created when the terminal side of an angle begins at the origin and passes through:
a) (2, -2)
b) (3, 3)
c) (-1.73, 1)
d) (3.46, 2)
3. How do you make triangles out of angles?
4. How would you find the lengths of the sides for the triangles created out of #2
5. What are the special right triangles?
4. What is a dilation? How much were the triangles in #2 dilated?
5. Dilate your triangles from #2 by a factor of 2, 5, 6

1st Entry:
We are beginning polar coordinates this week. Below is the link for the graphing paper should you need it.
2nd entry:
Here is a video in case you miss some of the classes on polar coordinates.
2nd Quarter:
Triple Eqn Matrix Intro: No solution Matrix: Triple Eqn Matrix:
-3y = 21 4x -3y +2z =12 -x -3y +2 =54
8x +y = 9 x + y- z = 3 4x+2y-3z=-32
y+z = 5 -2x-2y+2=5 2y +8z =78
