What to Focus On

  • All radii of a circle are equal in length
  • Diameter is the longest chord of a circle
  • The value of π ≈ 22/7 ≈ 3.14159

  • Degree measure of an arc = central angle subtended by the arc
  • Minor arc + Major arc = 360°
  • Semicircle has degree measure of exactly 180°

  • Congruent circles have equal radii
  • Congruent arcs need same angle AND same circle size
  • Concentric circles share the same center

Common Mistakes to Avoid

The longest chord of any circle is always equal to the radius

All chords are equidistant from the center of the circle

π (pi) equals exactly 22/7 in all calculations

Memory Tips

Definition of a circle

Circumference formula C = 2πr

Perpendicular from center bisects chord
