Lesson Review Available

Review the foundation notes with TTA Pro Mr.O before solving. If this skill drill is part of an anchor lesson, the notes stay available during practice.

Objective: By the end of this lesson you can solve every Digital SAT circle question across six levels: Level 1 recognition of radius, diameter, and the 360-degree whole, Level 2 setups for arc fractions, sector fractions, and the tangent-radius right angle, Level 3 core procedures with arc length, sector area, inscribed angles, and reading center and radius from a standard-form equation, Level 4 switching between graphs, diameter endpoints, tangent triangles, and equations, Level 5 completing the square without losing the balance and keeping both square-root branches, and Level 6 tangency conditions, represents-a-circle constraints, and the hand-vs-Desmos routing decision under time pressure.
