WebThe measure of each interior angle of a regular polygon can be calculated using the formula: Interior angle = (n - 2) x 180 / n. where n is the number of sides. For a polygon with 5 sides: Interior angle = (5 - 2) x 180 / 5 = 108 degrees. For a polygon with 18 sides: Interior angle = (18 - 2) x 180 / 18 = 160 degrees. For a polygon with 24 sides: WebSep 16, 2024 · A pentagon can be divided into three triangles, as seen here: Pentagon divided into 3 colored triangles If the sum of the measures of the interior angles in each of these three triangles...

WebJan 11, 2024 · Sometime during the mid 1600s, a mathematician felt the need for a descriptive word for a 12-sided polygon. The word dodecagon comes from the Greek, dōdeka-, which means 12, and + -gōnon, which means angled. Dodecagons can be regular, meaning all interior angles and sides are equal in measure. They can also be irregular, … WebIn a regular polygon all interior angles are equal in measure. So we can find each interior angle by dividing the sum of interior angles by the number of sides. Sum of interior angles Number of sides = 2340 ∘ 15 [Substitute the values] = 156 ∘ [Divide] Hence, each interior angle measures 156 ∘. Example 6: Find the measure of the unknown angle. autos hasselt
