The sum of the measures of the interior angles of a polygon can be calculated using the formula:
- Sum of interior angles = (n – 2) x 180°
Here, ‘n’ represents the number of sides in the polygon. For a regular heptagon, which has 7 sides, the calculation would be as follows:
- Identify the number of sides:
- n = 7
- Substitute n into the formula:
- Sum of interior angles = (7 – 2) x 180°
- Perform the subtraction:
- Sum of interior angles = 5 x 180°
- Now, multiply 5 by 180°:
- Sum of interior angles = 900°
Therefore, the total measure of the interior angles of a regular heptagon is 900 degrees.
This means that if you were to add up all the angles inside a heptagon, you would arrive at 900°. Each angle in a regular heptagon, where all angles are equal, would then be approximately 128.57 degrees.
