Learn and practice essential geometry skills. The answer to every problem, along with helpful notes, can be found at the back of the book. This volume focuses on fundamental concepts relating to circles, including chords, secants, tangents, and inscribed/circumscribed polygons. Topics include:

• radius, diameter, circumference, and area
  
• chords, secants, and tangents
  
• sectors vs. segments
  
• inscribed and circumscribed shapes
  
• the arc length formula
  
• degrees and radians
  
• inscribed angles
  
• Thales's theorem
  
• and an introduction to 3D objects, including the cube, prism, pyramid, sphere, cylinder, and cone
  

The author, Chris McMullen, Ph.D., has over twenty years of experience teaching math skills to physics students. He prepared this workbook of the Improve Your Math Fluency series to share his strategies for solving geometry problems and formulating proofs.
