Inscribed Angles of Circles

Curated and Reviewed by Lesson Planet

Relationships in circles build from the many connections made throughout the geometry course. The instructor in the video explains these connections as she builds the concept of inscribed angles. Using examples, the narrator highlights the connection between inscribed angles and the intercepted arcs.

Instructional Ideas

  • Have your classes construct inscribed angles within circles, then find and compare the measures of the inscribed angles and the arcs

Classroom Considerations

  • Expects learners have experience with central angles and arcs of circles
  • Pupils should be proficient with angle relationships within triangles
  • The 17th installment in a series of 40 video lessons
  • This video is hosted on YouTube

Pros

  • Instructor places an emphasis on vocabulary throughout the video
  • Develops the relationship between arcs and angles

Cons

  • Examples do not include context
