WebApr 7, 2024 · Neighboring angles or adjacent interior angles are two internal angles that share a common side. All five sides of a regular pentagon are equal, as are all five angles. As a result, the formula below gives the measurement of each internal angle of a regular pentagon. Each internal angle is measured as (n – 2) 180°/n = 540°/5 = 108°. WebIf you make them all adjacent to one another, they will form 180 degrees. To prove this, let's say we have a triangle ABC. We could create a line parallel to BC through point A. Using the angle pair relationships of parallel lines, we would find that there are two pairs of alternate interior angles that are congruent to each other.

WebInterior Angle = 180° − 360°/n Which can be rearranged like this: Interior Angle = 180° − 360°/n = (n × 180° / n) − (2 × 180° / n) = (n−2) × 180°/n So we also have this: Interior Angle = (n−2) × 180° / n Example: What is the interior angle of a regular octagon? A regular octagon has 8 sides, so: Exterior Angle = 360 ° / 8 = 45°

WebTo find: The measure of each interior angle of a regular polygon of 23 sides. The number of sides of the given polygon is n = 23.
