CIRCLE EQUATIONS – ALGEBRA II GEOMETRY
ACTIVITY OVERVIEW:
Master the equation of a circle through interactive drag-and-drop activities. Students work with center-radius form, identify circle parameters, and graph circles on the coordinate plane.
LEARNING OBJECTIVES:
• Write equations of circles in standard form
• Identify center and radius from equations
• Graph circles on coordinate planes
STANDARDS ALIGNMENT:
• TX TEKS Geometry G.12.E – Show the equation of a circle with center (h, k) and radius r is (x-h)² + (y-k)² = r²
SKILLS DEVELOPED:
Conic Sections, Algebraic Manipulation, Graphing Skills, Mathematical Relationships
GRADE LEVELS: 10th-12th Grade (Algebra II, Geometry)
ACTIVITY TYPE: Drag and Drop
