Formulas for Polygons in 8th Grade

In 8th grade, students learn about various polygons and their properties. Here are some important formulas for polygons:

1. Perimeter of a Polygon: - The perimeter of a polygon is the sum of the lengths of all its sides. - For a regular polygon with n sides, where each side has length s, the perimeter P is given by: P = n * s.

2. Area of a Polygon: - The area of a polygon can be calculated using different formulas based on the type of polygon. - For a regular polygon with apothem (a) and perimeter (P), the area A is given by: A = 1/2 * a * P.

3. Sum of Interior Angles: - The sum of the interior angles of a polygon can be calculated using the formula: Sum of interior angles = (n - 2) * 180 degrees, where n is the number of sides.

4. Exterior Angle of a Polygon: - The exterior angle of a regular polygon is given by: Exterior angle = 360 degrees / n, where n is the number of sides.

These are some fundamental formulas for polygons that are typically covered in 8th-grade geometry. Understanding these formulas is essential for solving problems related to polygons and their properties.
