Instructional Ideas

• After introducing each rule, have students explain the rule to a classmate in their own words
• Pause the video after each rule to ask and answer clarifying questions

Classroom Considerations

• Learners should be familiar with tangent and secant lines
• The 19th installment in a series of 40 video lessons

• This video is hosted on YouTube

Pros

• Connects the segment and angle rules of secant and tangent lines to the formation of similar triangles

Cons

• Explanation of the tangent/secant rules at the beginning is difficult to follow
