## Student Learning Targets:

- Circles 1: I understand the derivation for the equation of a circle on the coordinate plane.
- Habit 4: I can construct mathematical models.
- Habit 6: I attend to precision.
- Habit 7: I look for and can make use of structures and patterns.

## Opener: Draw and label 2 coordinate planes. Then:

- Graph the circle with center (2, -2) and a radius of 5. By looking at your graph, estimate the y-value when x=6.
- Graph the circle with center (3,1) and a radius of 3. By looking at your graph, estimate the y-value when x = 4.

## Discussion Questions!

## Back to the opener — let’s check our estimates.

- How can we use the Pythagorean Theorem?
- How can we build right triangles in circles?
