Web7. 900°. Octagon. 8. 1080°. The measure of each internal angle in a regular polygon is found by dividing the total sum of the angles by the number of sides of the polygon. For … WebInterior angle = 180° - exterior angle. Given, interior angle = 108° So, 108° = 180° - exterior angle. Exterior angle = 180° - 108° = 72° Number of sides of a polygon = 360°/exterior angle = 360°/72° = 5. Therefore, the number of sides of a polygon is 5. Try This: Each interior angle of a polygon is 118°. Find the number of sides of ...

WebNov 22, 2024 · with regular polygons it is best to work with the exterior angles since the sum of exterior angles is #360^o#. one exterior angle = #180-# one interior angle one … WebJan 12, 2010 · A regular polygon with interior angles measuring 165 degrees each will have exterior angles measuring 15 degrees each, since each pair of interior/exterior angles forms a linear pair whose measures total 180 degrees. For any polygon, the sum of the exterior angles is 360 degrees. You can find how many sides, and therefore vertices, … ionic cornwall
Interior Angles of a Polygon: Definition, Formulas, Theorems
WebInterior angle = 180° - exterior angle. Given, interior angle = 108° So, 108° = 180° - exterior angle. Exterior angle = 180° - 108° = 72° Number of sides of a polygon = … WebJan 2, 2024 · So, the sum of interior angles of the polygon = n × 180° – 360°. = (n – 2) × 180°. Thus, the sum of interior angles of the polygon = (n – 2) × 180°. The measure of each interior angle of a regular polygon = … WebMeasure of each interior angle of regular polygon = \(\frac{(n-2)~\times~180^\circ}{n}\) Let us find the measure of interior angle of a regular quadrilateral: The sum of the interior angles of a quadrilateral is 360° and the number of sides of a quadrilateral is 4. ionic corinthian columns
