Mr. Standen and Mrs. Thomas’s 3^rd hour CAHS Geometry class students are studying the equation of a circle (x-h)² + (y-k) ² = r²and then learning how to sketch the circle on the coordinate plane and how to find the center and the radius of the circle based on the equation. Students are demonstrating their knowledge on white boards and then completing practice on additional problems to further their understanding of the concept.
