SAT Math Lesson Plan 26: Circle Theorems and Tangents

In SAT Math Lesson 26, students will explore important geometric theorems involving circles, tangents, and inscribed angles. This lesson covers:

• The relationships between tangents and radii, including perpendicularity at the point of contact,
• The Inscribed Angle Theorem and how it relates to central angles,
• The construction and application of inscribed circles in triangles, and
• Theorems involving intersecting chords, secants, and tangents.

Through a blend of geometric reasoning and algebraic application, students will develop a deeper understanding of how circle theorems appear on the SAT. Each concept is explained with step-by-step examples and real-world contexts to reinforce comprehension. This lesson aligns with key Common Core standards for high school geometry and prepares students to tackle advanced SAT geometry questions with confidence.
