Polygons Quiz

Interior Angles of a Polygon

• The sum of the interior angles of a polygon can be calculated using the formula: (n - 2) × 180°, where n is the number of sides.
• For a polygon with 10 sides, the sum is (10 - 2) × 180° = 8 × 180° = 1440°.

Regular Polygon Characteristics

• A regular polygon has all sides of equal length and all angles of equal measure, making it both equilateral and equiangular.

Concave Polygon Definition

• A concave polygon is defined by at least one interior angle that measures greater than 180°. This feature causes the shape to "cave in" towards the interior.

Area Calculation for Regular Polygons

• The area of a regular polygon can be calculated using various formulas, commonly: Area = (1/2) × Perimeter × Apothem or Area = (n × s^2) / (4 × tan(π/n)), where s is the length of a side.

Minimum Polygon Sides

• A polygon must have a minimum of three sides to be classified as such; shapes with fewer than three sides do not enclose a space.
