a closed plane figure bounded by three or more straight sides that meet in pairs in the same number of vertices, and do not intersect other than at these vertices. The sum of the interior angles is (n--2) × 180° for n sides; the sum of the exterior angles is 360°. A regular ...
Best Answer The sum of the interior angles of any regular polygon of n sides is equal to 180(n - 2) degrees. 1440 degrees Wiki User ∙11yago This answer is: Add your answer: Earn +20pts Q:What is the sum of the measures of the angle of a decagon?
How do I calculate the exterior angle of a decagon? To determine the exterior angle of a regular decagon: Recall the formula for the sum of interior angles: n× 180° - 360°, where n is the number of sides. In our case n = 10, so 10 × 180° - 360° = 1440°. There are ...
To express the angular measurement of the angle of a regular decagon in degrees and radians, we can follow these steps:Step 1: Calculate the sum of the interior angles of the decagon. The formula for the sum of the interior ang
