- Chapter 7 - Area
### Chapter 7 - Area

Standards:

Given a geometric figure and a rotation, refection, or translation, draw the transformed figure using, e.g., graph paper, tracing paper, or geometry software. G-C.5

Know precise definitions of angle, circle, perpendicular line, parallel line, and line segment, based on the undefined notions of point, line, distance along a line, and distance around a circular arc. G-CO.1

Construct and equilateral triangle, a square, and a regular hexagon inscribed in a circle. G-CO.13

Use coordinates to compute perimeters of polygons and areas of triangles and rectangles. G-GPE.7

Use geometric shapes, their measures, and their properties to describe objects. G.MG.1

Derive the formula A = 1/2 ab sine@ for the area of a triangle by drawing an auxiliary line from a vertex perpendicular to the opposite side. G-SRT.9

Use units as a way the understand problems and to guide the solution of multi-step problems; choose and interpret units consistently in formulas; choose and interpret the scale and origin in graphs and data displays. N-Q.1

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. S-CP.1

- Chapter 8 - Similarity
### Chapter 8 - Similarity

Standards:

Create equations and inequalities in one variable and use them to solve problems. A-CED.1

Use congruence and similarity criteria for triangles to solve problems and to prove relationships in geometric figures. G.GPE.5

Prove theorems about triangles. G-SRT.4

Use congruence and similarity criteria for triangles to solve problems and to prove relationships in geometric figures. G-SRT.5

- Chapter 9 - Right Triangle Trigonometry
### Chapter 9 - Right Triangle Trigonometry

Standards:

Prove theorems about triangles. G-SRT.4

Understand that by similarity, side ratios in right triangles are properties of the angels in the triangle, leading to definitions of trigonometric ratios for acute angles. G-SRT.6

Explain and use the relationship between the sine and cosine of complementary angles. G-SRT.7

Use trigonometric shapes, their measures, and their properties to describe objects. G-SRT.8

Use geometric shapes, their measures, and their properties to describe objects. G-MG.1

Recognize vector quantities as having both magnitude and direction. Represent vector quantities by directed line segments, and use appropriate symbols for vectors and their magnitudes. N-VM.1

Add and subtract vectors. N-VM.4

Add vectors end-to-end, component-wise, and by the parallelogram rule. Understand that the magnitude of a sum of two vectors is typically not the sum of the magnitudes. N-VM.4a

- Chapter 10 - Surface Area and Volume
### Chapter 10 - Surface Area and Volume

Standards:

Give and informal argument for the formulas for the circumference of a circle, area of a circle, volume of a cylinder, pyramid, and cone. G-GMD.1

Give and informal argument using Cavalieri's principle for the formulas for the volume of a sphere and other solid figures. G-GMD.2

Use volume formulas for cylinders, pyramids, comes and spheres to solve problems. G-GMD.3

Identify the shapes of two-dimensional cross-sections of three-dimensional objects, and identify three-dimensional objects generated by rotations of two-dimensional objects. G-GMD.4

Use geometry shapes, their measures, and their properties to describe objects. G-MG.1

Apply concepts of density based on areas and volume in modeling situations. G-MG.2

Use units as a way to understand problems and to guide the solution of multi-step problems; choose and interpret units consistently in formulas; choose and interpret the scale and origin in graphs and data displays. N-Q.1

- Chapter 12- Transformations
### Chapter 12- Transformations

Standards:

Represent transformations in the plane using, e.g., transparencies and geometry software; describe transformations as functions that take points in the plane as inputs and give other points as outputs. Compare transformations the preserve distance and angle to those that do not. G-CO.2

Given a rectangle, parallelogram, trapezoid, or regular polygon, describe the rotations and reflections that carry it onto itself. G-CO.3

Develop definitions of rotations, reflections, and translations in terms of angles, circles, perpendicular lines, parallel lines, and line segments. G-CO.4

Given a geometric figure and a rotation, reflection, or translations, draw the transformed figure using, e.g., graph paper, tracing paper, or geometry software. Specify a sequence of transformations that will carry a given figure onto another. G-CO.5

Use geometric descriptions of rigid motions to transform figures and to predict the effect of a given rigid motion on a given figure; give two figures, use the definition of congruence in terms of rigid motions to decide if the are congruent. G-CO.6
