Central Angles Matching Activity – High School Geometry

This Central Angles Matching Activity gives high school geometry students targeted practice identifying and working with central angles and intercepted arcs. The focus is on conceptual understanding and algebraic reasoning with central angles.

How it works

Students solve each problem, then match the correct numerical answer by placing the corresponding letter in the answer box. Extra answer choices are included and not all of them are used, which requires careful reasoning.

What’s included

• 9 central angle problems in a matching format
• Printable student worksheet
• Answer key
• Teacher notes with common student errors, differentiation, and extension suggestions

The problems include:

• Finding central angle measures
• Finding intercepted arc measures
• Solving for missing angle measures
• Solving algebraic expressions involving central angles

Skills covered

• Identifying central angles
• Using the relationship between central angles and intercepted arcs
• Applying the 360° angle sum around a point
• Solving algebraic expressions in circle geometry
• Distinguishing central angles from other angle types

Quick facts

• Grades: 8–10
• CCSS: HSG-C.A.2
