Angle Properties of Polygons

(n - 2) \times 180 = 720

Number of sides (n)6

Interior angle sum720°

Each interior angle120.0°

Each exterior angle60.0°

Number of sides6

Set the polygon to a triangle (3 sides) — confirm the interior angle sum is 180°
Set the polygon to a hexagon (6 sides) — confirm each interior angle is 120°
Set the polygon to a pentagon (5 sides) — confirm the interior angle sum is 540°
Try any number of sides and confirm all exterior angles still sum to 360° (n × exterior angle)
Push the polygon to its maximum number of sides — confirm each interior angle reaches 150°
