  2. Apply the relationship: Each exterior angle = 360°/n.
  3. The result is 60 degrees, rounded for display.

How to interpret your result

Uses the equal turning angles of a regular convex polygon.

A perimeter measures the outline; area measures the enclosed surface. Regular polygon tools assume equal sides and angles. For a parallelogram or trapezoid, use the height perpendicular to the selected base.
