The sum of interior angles in a pentagon is calculated using the general rule: Sum of Interior Angles = (n – 2) × 180°. For a pentagon with 5 sides, the sum of interior angles is (5 – 2) x 180° = 3 x 180° = 540°. This formula applies to regular and irregular pentagons, as they have interior angles of 108° and exterior angles of 72°.
The sum of interior angles in a pentagon is always equal to 540 degrees, regardless of whether the pentagon is regular or irregular. For example, if n=5, the sum of interior angles is (5−2)×180∘ = 540∘.
Angles in a pentagon are the angles in a five-sided polygon (2D shape). The sum of interior angles of a regular pentagon is 54 0 ∘, while the sum of interior angles of a regular pentagon is 540∘.
In summary, the sum of interior angles in a pentagon is 540°, which is equal to the sum of the angles in a regular pentagon. The sum of interior angles in a regular pentagon is 54 0 ∘, and the sum of interior angles in a regular pentagon is 540∘.
