- Lesson Plan →Objectives, pacing and practice, built from this lesson's brief.
- Guided Notes →One page your students fill in and keep.
- Exit Ticket →Three items at the end of class. No student accounts.
- Re-teach →After an exit ticket: who missed what, and what to do tomorrow.
- Homework →Assign practice; it grades itself.
"Use definitions, properties, and theorems relating to circles and parts of circles such as radii, diameters, tangents, angles, arc lengths, and sector areas to solve problems."
"... use the distance formula in problems related to circles."

"Use definitions, properties, and theorems relating to circles and parts of circles such as radii, diameters, tangents, angles, arc lengths, and sector areas to solve problems."
"... use the distance formula in problems related to circles."
What you'll learn
- Identify and apply the tangent-radius perpendicularity property to find unknown lengths and angles
- Use the theorem that two tangent segments from the same external point are congruent
- Calculate the distance from a circle's center to a chord using the perpendicular bisector relationship
- Apply chord-chord relationships, including the intersecting chords length theorem
