Circles (Geometry - Unit 12)

Get your head aROUND circles with a unit that has all the important info you need!

This is a unit bundle that currently contains presentation notes, student follow-along notes handouts, glossary, glossary cards, 7 practice worksheets, 6 section quizzes, a study guide, and a unit test (multiple-choice & short-answer versions). Other items will be added over time, and the price will be modified as necessary during this process.

I am and have been a high school Geometry teacher for 20+ years, and all of the content has been used in my classroom.

The notes introduce each concept along with a few examples. They are in-depth enough to cover a topic well, and, at the same time, are brief enough to allow you to add related topics/examples of your choice without being overwhelming or stifling your own creativity/flexibility.

The topics included are:

1) Circle Basics - including identifying parts of a circle, applying the relationships between angles and arcs, and converting between radians and degrees

2) Distance & Area in a Circle - including the circumference of a circle, the area of a circle, arc length, sector area, and segment area

3) Angles Associated with Circles - including angles formed by lines intersecting inside/outside of a circle, angles formed by a tangent & radius, opposite angles of an inscribed quadrilateral, angles formed by a tangent and a chord, and an angle inscribed in a semicircle

4) Segments Associated with Circles - including the bisection of a chord/arc when the diameter is perpendicular to the chord, the congruence of two tangents intersecting outside a circle, chords equidistant from the center, and segment relationships for intersections inside or outside of a circle

5) Equations & Graphs of Circles - including multiple combinations of given information to relate the radius/diameter, center, equation, and graph of a circle

6) Vocabulary - 45 terms/theorems/postulates

The preview contains a sampling of the notes, assessments, and practice.
