Given the measure of an interior angle of a regular polygon, how many sides does the polygon have?
Elis [28]

The sides of a regular polygon with a known interior angles can be found as follows:

Interior Angle = (n−2) × 180° / n

<h3 /><h3 /><h3>Regular polygon</h3>

A regular polygon is a polygon that have equal sides and equal angles.

A regular polygon has the following angles:

  • interior angles
  • exterior angles

According to the question, the interior angles are given. To know the number of sides of polygon can be calculated as follows:

Note the interior and the exterior angles add up to 180 degrees.

Therefore,

Interior Angle = 180° − Exterior Angle

Exterior angle = 360°/n

Interior Angle = 180° − 360°/n

n = number of sides

Finally,

  • Interior angle = (n−2) × 180° / n
