CCSS.Math.HSG.C.A.3
Primary
Construct the inscribed and circumscribed circles of a triangle, and prove properties of angles for a quadrilateral inscribed in a circle.Reason: This standard supports the project objective of constructing circumcenters, incenters, inscribed circles, and exploring cyclic properties of quadrilaterals, enhancing geometric understanding in circle art designs.
CCSS.Math.HSG.C.B.4
Primary
Define radians measure of an angle as the constant of proportionality between the length of an arc and its radius. Derive the formula for the area of a sector and apply it in solving problems.Reason: This aligns with using radians to express angle measures and understanding the significance of radians and tau in circle measurements.
