This is the same regardless of how many sides the polygon has. The exterior angles of a triangle add up to 360°; the exterior angles of a decagon also add up to 360°. Exterior Angle Sum of a Polygon = 360 degrees Suggested Reading How to Find Pi Using Regular Polygons An article a...
Sum of Interior Angles = (n−2) × 180° Each Angle (of a Regular Polygon) = (n−2) × 180° / nHere's an example to make it clearer:Example: What about a Regular Decagon (10 sides) ? Sum of Interior Angles = (n−2) × 180° = (10−2) × 180° = 8 × 180°...

interior angle, we would know the measure of all interior angles. Since the exterior angles of ANY polygon add up to 360 degrees, the formula for finding the measure of EACH exterior angle is… EXAMPLE # 2 : What are the measures of the exterior angles of a regular polygon with 6 sides...
In geometry, we define a polygon as a two-dimensional shape that has straight sides that meet at points called vertices of the polygon. At each vertex of a polygon, two angles are formed; one inside the polygon, and one outside the polygon. We have special names for each of these ...
By definition, a pentagon is a polygon with 5 sides, 5 internal angles, and 5 external angles. The sum of interior angles of a polygon is given by $$(n-2)180^{\circ} $$ where {eq}n{/eq} refers to the number of sides of a polygon. In the case of pentagon, the ...
