Interior Angles - Definition, Meaning, Theorem, Examples

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° WebAn Interior Angle is an angle inside a shape. Another example: When we add up the Interior Angle and Exterior Angle we get a Straight Angle (180°), so they are … WebAn interior angle is formed by the sides of a polygon and is inside the figure. The 3 3 interior angles in every triangle add up to 180 ^\circ 180∘. Example: 109^\circ + 23^\circ + 48^\circ = 180^\circ 109∘ + 23∘ + 48∘ = … shorebirds salisbury maryland
