MediumApply properties of tangent lines to circles (Medium)
18 problems · 20-25 minutes · Skills: circles, tangents, geometry
About This Worksheet
This medium-level worksheet contains 18 problems designed for 10th Grade students practicing tangent lines. Medium worksheets introduce larger numbers and varied question formats to deepen understanding and build fluency.
Tangent line properties have direct applications in physics (tangential velocity, circular motion) and engineering (gear systems, pulleys, track design). They also introduce students to limit-based thinking — a tangent line touches a circle at exactly one point — which foreshadows calculus concepts.
- Prove and apply the theorem that a tangent is perpendicular to the radius at the point of tangency
- Apply the Two-Tangent Theorem to find equal tangent segment lengths
- Solve problems involving angles and segments formed by tangents and secants
- Calculate the length of a tangent segment from an external point using the Pythagorean Theorem
- Apply the secant-tangent angle theorem to find intercepted arc measures
How to Solve: Worked Example
- Read the problem carefully.
- Identify what is being asked.
- Use what you know to find the answer.
- Check your work.
