The standards that apply to this lesson are:

Standards CCSSM/Maryland College and Career Ready Standards Previous standards that provided prior knowledge: CCSS.MATH.CONTENT.7.G.B.4 Know the formulas for the area and circumference of a circle and use them to solve problems; give an informal derivation of the relationship between the circumference and area of a circle. Current standard being addressed: CCSS.MATH.CONTENT.HSG.C.A.2 Identify and describe relationships among inscribed angles, radii, and chords. Include the relationship between central, inscribed, and circumscribed angles; inscribed angles on a diameter are right angles; the radius of a circle is perpendicular to the tangent where the radius intersects the circle. Standard to be addressed in the next lesson: CCSS.MATH.CONTENT.HSG.C.A.3 Construct the inscribed and circumscribed circles of a triangle, and prove properties of angles for a quadrilateral inscribed in a circle Standards for Mathematical Practice Model with mathematics. Use appropriate tools strategically. Look for and make use of structure.
