Special Quadrilateral Clean Up
Lesson 6 of 8
Objective: Students will be able to define special quadrilaterals, triangles, and circles terms.
Notes: Circles Vocabulary
Since this is an Introduction to Geometry unit, students need to know basic circles vocabulary. I gives notes on the following terms:
- Circle, radius, diameter
- Congruent circles, concentric circles
- Arc of a circle, endpoints
- Semicircle, minor arc, major arc
- Central angle, arc measure
After students write these definitions and draw sketches to match, I pass out examples and non-examples of chords, diameters, and tangents. I ask students to write a good definition for each term. I call on student volunteers to read their group's definition for each of these terms and make edits if necessary.
