Geometry
The Fine Print
Course Goals

Achieve proficiency in describing defined and undefined terms to visualize geometric concepts

Use formulas to find midpoints, distances, and bisectors of lines

Describe angle properties and relationships to determine characteristics of line

Given a geometric figure, perform transformations, tessellations, and dilations on a coordinate plane

Justify relationships of triangles through mathematical arguments using congruence postulates

Justify properties of lines through mathematical arguments using angle theorems

Understand and prove properties in order to classify polygons

Use theorems and postulates to prove properties of circles

Use inductive reasoning and logic to draw conclusions and formulate conjectures

Use formulas to find the perimeter, area, and volume of 2D and 3D figures
Topics Covered

Relationships and properties of points, lines, planes and angles

Properties of polygons including classification, measurements of sides and angles, perimeter, area, and volume

Surface area of 3D shapes

Properties of circles including circumference and measurements of parts of a circle including arcs, chords, angles and segments

Inductive reasoning, deductive reasoning and logic to formulate proofs

Transformations of figures including reflections, translations, rotations and dilations

Relationships and properties of triangles including congruence, similarity, and classifications in order to construct proofs

Trigonometry involving right triangles, the Triangle Inequality, The Pythagorean Theorem, The Law of Sines and The Law of Cosines

Course Resources
Textbook

Glencoe Geometry (2018)

Hardcopy textbook loaned free through Blue Tent OnLoan
Web Resources

WebAssign (approx. $11). The instructor will provide ordering instructions.

Glencoe digital companion to Geometry text (ebook & web resourcescost is included in tuition)

GeoGebra. Free application for students to visualize 2D and 3D geometric shapes/properties

Desmos.com. Free online graphing calculator for use in sections involving equations of lines and algebraic functions
Calculator

A graphing calculator is not required, although a scientific calculator will come in handy.

If students plan to purchase a graphing calculator, we recommend the TI84 series.
Technical Resources
We use ZOOM for live classes. Students need:

A reliable internet connection

A computer with a webcam

Recommended: a headset with a microphone (builtin computer microphone will work if needed)

Requested: students who attend classes live are asked to keep their webcams on during class
