The fundamental purpose of the course in Geometry is to formalize and extend students’ geometric experiences from the middle grades. Students explore more complex geometric
situations and deepen their explanations of geometric relationships, moving towards formal mathematical arguments. Important differences exist between this Geometry course
and the historical approach taken in Geometry classes. For example, transformations are emphasized early in this course. Close attention should be paid to the introductory content
for the Geometry conceptual category found in the high school standards. The Standards for Mathematical Practice apply throughout each course and, together with the content
standards, prescribe that students experience mathematics as a coherent, useful, and logical subject that makes use of their ability to make sense of problem situations. The critical
areas, organized into five units are as follows.
Unit 1-Congruence, Proof, and Constructions: In previous grades, students were asked to draw triangles based on given measurements. They also have prior experience with rigid
motions: translations, reflections, and rotations and have used these to develop notions about what it means for two objects to be congruent. In this unit, students establish
triangle congruence criteria, based on analyses of rigid motions and formal constructions. They use triangle congruence as a familiar foundation for the development of formal
proof. Students prove theorems—using a variety of formats—and solve problems about triangles, quadrilaterals, and other polygons. They apply reasoning to complete geometric
constructions and explain why they work.
Unit 2- Similarity, Proof, and Trigonometry: Students apply their earlier experience with dilations and proportional reasoning to build a formal understanding of similarity. They
identify criteria for similarity of triangles, use similarity to solve problems, and apply similarity in right triangles to understand right triangle trigonometry, with particular attention
to special right triangles and the Pythagorean Theorem. Students develop the Laws of Sines and Cosines in order to find missing measures of general (not necessarily right) triangles,
building on students’ work with quadratic equations done in the first course. They are able to distinguish whether three given measures (angles or sides) define 0, 1, 2, or infinitely
many triangles.
Unit 3- Extending to Three Dimensions: Students’ experience with two-dimensional and three-dimensional objects is extended to include informal explanations of circumference,
area and volume formulas. Additionally, students apply their knowledge of two-dimensional shapes to consider the shapes of cross-sections and the result of rotating a twodimensional object about a line.
Unit 4- Connecting Algebra and Geometry Through Coordinates: Building on their work with the Pythagorean theorem in 8th grade to find distances, students use a rectangular
coordinate system to verify geometric relationships, including properties of special triangles and quadrilaterals and slopes of parallel and perpendicular lines, which relates back to
work done in the first course. Students continue their study of quadratics by connecting the geometric and algebraic definitions of the parabola.
Unit 5-Circles With and Without Coordinates: In this unit students prove basic theorems about circles, such as a tangent line is perpendicular to a radius, inscribed angle theorem,
and theorems about chords, secants, and tangents dealing with segment lengths and angle measures. They study relationships among segments on chords, secants, and tangents as
an application of similarity. In the Cartesian coordinate system, students use the distance formula to write the equation of a circle when given the radius and the coordinates of its
center. Given an equation of a circle, they draw the graph in the coordinate plane, and apply techniques for solving quadratic equations, which relates back to work done in the first
course, to determine intersections between lines and circles or parabolas and between two circles.

MAFS.912.S-CP.1.2: Understand that two events A and B are independent if the

MAFS.912.S-CP.1.4: Construct and interpret two-way frequency tables of data when two
categories are associated with each object being classified. Use the two-way table as a

Suggested Literacy & English Language Standards
MAFS.912.A-APR.1: Perform arithmetic operations on polynomials.
 MAFS.912.A-APR.1.1: Understand that polynomials form a system analogous to the
integers, namely, they are closed under the operations of addition, subtraction, and
multiplication; add, subtract, and multiply polynomials.
MAFS.912.A-APR.2: Understand the relationship between zeros and factors of polynomials.
 MAFS.912.A-APR.2.3: Identify zeros of polynomials when suitable factorizations are
available, and use the zeros to construct a rough graph of the function defined by the
polynomial.
MAFS.912.A-SSE.1: Interpret the structure of expressions.
 MAFS.912.A-SSE.1.1: Interpret expressions that represent a quantity in terms of its
context.
a. Interpret parts of an expression, such as terms, factors, and coefficients.
b. Interpret complicated expressions by viewing one or more of their parts as a single
entity. For example, interpret as the product of P and a factor not depending on P.
 MAFS.912.A-SSE.1.2: Use the structure of an expression to identify ways to rewrite it. For
example, see 𝑥 4 − 𝑦 4 as (𝑥²)² – (𝑦²)², thus recognizing it as a difference of squares that
can be factored as (𝑥² – 𝑦²)(𝑥² + 𝑦²).
MAFS.912.A-SSE.2: Write expressions in equivalent forms to solve problems.
 MAFS.912.A-SSE.2.3: Choose and produce an equivalent form of an expression to reveal
and explain properties of the quantity represented by the expression.
a. Factor a quadratic expression to reveal the zeros of the function it defines.
MAFS.912.F-IF.3: Analyze functions using different representations.
 MAFS.912.F-IF.3.8: Write a function defined by an expression in different but equivalent
forms to reveal and explain different properties of the function.
Use the process of factoring and completing the square in a quadratic function to show zeros,
extreme values, and symmetry of the graph, and interpret these in terms of a context.
LAFS.910.WHST.2.4: Produce clear and coherent writing in which
the development, organization, and style are appropriate to task,
purpose, and audience.
ELD.K12.ELL.MA.1: English language learners communicate
information, ideas and concepts necessary for academic success
in the content area of Mathematics.

Suggested Mathematical Practice Standards
MAFS.K12.MP.7.1: Look for and make use of structure.
 What patterns do you see?
 Can you look at the individual parts/terms of the polynomials
to help solve the problem?
MAFS.K12.MP.8.1: Look for and express regularity in repeated
reasoning.
 Are there generalizations you can make about multiplying
binomials?
 Why are some products of binomials referred to as special
cases?
