Understanding Angles in a Pentagon
A pentagon is a polygon with five sides, and each internal angle is formed by the intersection of two adjacent sides. The sum of the interior angles of a pentagon is always 540 degrees. This can be calculated using the formula (n-2) × 180, where n is the number of sides. For a pentagon, this becomes (5-2) × 180 = 540 degrees.
Types of Angles in a Pentagon
There are two types of angles in a pentagon: interior angles and exterior angles. Interior angles are the angles formed by the intersection of two adjacent sides, while exterior angles are the angles formed by the extension of two adjacent sides.
- Interior Angles: The interior angles of a pentagon are the angles formed by the intersection of two adjacent sides. The sum of the interior angles of a pentagon is always 540 degrees.
- Exterior Angles: The exterior angles of a pentagon are the angles formed by the extension of two adjacent sides. The sum of the exterior angles of a pentagon is always 360 degrees.
