GEOMETRY – CIRCLES (G.C)
- G.C.A.1 Use proportional relationships between the area of a circle and the area of a sector within the circle to solve problems in a real-world context.
GEOMETRY – CONGRUENCE (G.CO)
- G.CO.A.1 Describe transformations as functions that take points in the plane (pre-image) as inputs and give other points (image) as outputs. Compare transformations that preserve distance and angle measure to those that do not, by hand for basic transformations and using technology for more complex cases.
- G.CO.A.2 Given a rectangle, parallelogram, trapezoid, or regular polygon, determine the transformations that carry the shape onto itself and describe them in terms of the symmetry of the figure.
- G.CO.A.3 Develop definitions of rotations, reflections, and translations in terms of angles, circles, perpendicular lines, parallel lines, and line segments.
- G.CO.A.4 Given a geometric figure, draw the image of the figure after a sequence of one or more rigid motions, by hand and using technology. Identify a sequence of rigid motions that will carry a given figure onto another.
- G.CO.B.5 Given two figures, use the definition of congruence in terms of rigid motions to determine informally if they are congruent.
- G.CO.B.6 Use the definition of congruence in terms of rigid motions to show that two triangles are congruent if and only if corresponding pairs of sides and corresponding pairs of angles are congruent.
- G.CO.B.7 Explain how the criteria for triangle congruence (ASA, SAS, AAS, SSS, and HL) follow from the definition of congruence in terms of rigid motions.
- G.CO.C.8 Use definitions and theorems about lines and angles to solve problems and to justify relationships in geometric figures.
- G.CO.C.9 Use definitions and theorems about triangles to solve problems and to justify relationships in geometric figures.
- G.CO.C.10 Use definitions and theorems about parallelograms to solve problems and to justify relationships in geometric figures.
- G.CO.D.11 Perform formal geometric constructions with a variety of tools and methods (compass and straightedge, string, reflective devices, paper folding, dynamic geometric software, etc.).
- G.CO.D.12 Use geometric constructions to solve geometric problems in context, by hand and using technology.

G.S
- G.S.CP.A.1.a Describe events as subsets of a sample space (the set of outcomes) using characteristics (or categories) of the outcomes, or as unions, intersections, or complements of other events ("or", "and", "not").
- G.S.CP.A.1.b Flexibly move between visual models (Venn diagrams, frequency tables, etc.) and set notation.
- G.S.CP.B.2 Find the conditional probability of A given B as the fraction of B’s outcomes that also belong to A and interpret the answer in terms of the given context.

- G.S.CP.B.3.b Apply the Addition Rule to solve problems and interpret the answer in terms of the given context.
- G.S.CP.C.4 Calculate probabilities using geometric figures.
GEOMETRY – SIMILARITY, RIGHT TRIANGLES, AND TRIGONOMETRY (G.SRT)
- G.SRT.A.1 Use properties of dilations given by a center and a scale factor to solve problems and to justify relationships in geometric figures.
- G.SRT.A.2 Define similarity in terms of transformations. Use transformations to determine whether two figures are similar.
- G.SRT.B.3 Use congruence and similarity criteria for triangles to solve problems and to justify relationships in geometric figures.
