I/D #1: Unit N Concept 7- Unit Circle Derivation

Inquiry Activity Summary

1. 30* Right Triangle

2. 45* Right Triangle

3. 60* Right Triangle



4. This activity showed me where the values from the unit circle came from which was the special right triangles. Getting the three triangles let me know that they are the same in each quadrant so it leads to knowing the entire unit circle

Different angles in different quadrants

5. The triangles in the videos are all in the first quadrant and the ordered pairs are positive. Redrawing the 30* angle in the second quadrant made the x values become negative. The 45* angle in the third quadrant makes both x and y values become negative.The 60* angle in the fourth quadrant makes the y values become negative.

Inquiry Activity Reflection

1. The coolest thing I learned from this activity was learning where the numbers for the unit circle come from. I now know if I'm given some sort of right angle that I can solve for the points.

2. This activity will help me in this unit because this is the first time that I have been introduced to the unit circle and it is a great way to remember the values of the points of the graph.

3. Something I never realized before about special right triangles and the unit circle is the points are directly correlated and that a triangle will let me know the points on the graph.
