### CCSS Geometry

Textbook*: College Preparatory Mathematics: Geometry Connections

Geometry is the second math course available for high school credit in Portland Public Schools.

Students in this course will need a scientific calculator (NOT a graphing calculator) for use in completing homework problems.

The following is a summary of the topics covered in Geometry.  Refer to the appropriate Geometry calendar for more detailed information.

 Chapter Topics covered Approximate timeline 1 Transformations: reflections, rotations, translations, dilations; introduction to characteristics of shapes September 2 Angle properties: vertical, complementary, supplementary, alternate/corresponding, interior/exterior September 3 Similarity and proportion: length ratios of similar figures; conditions for triangle similarity; introduction to flowchart proof October 4 Introduction to right triangle trigonometry: slope and tangent ratio October 5 Right triangle trigonometry: sine, cosine, and inverses; Pythagorean triples November 6 Conditions for triangle congruence; flowchart proofs December 7 Properties of quadrilaterals; more proof; coordinate geometry December/January 8 area ratios of similar figures; circles: area and circumference January/February 9 Volume and surface area of prisms and cylinders; volume ratios of similar figures; constructions February 10 Circle properties: radius/diameter, arc, tangent, chord; equation of a circle March 11 Volume and surface area of pyramids, cones, and spheres; circle properties: tangent, arc, and secant March/April 12 Conics; conditional probability supplement April/May

*Some schools use Key Curriculum Press: Discovering Geometry instead of CPM: Geometry Connections.  The topics covered should be the same, but the timeline may be different.
