The sum of the interior angles of a polygon is equal to the formula below with the number of sides represented by (n): $$\text{Sum of Interior Angles} = (n -2)\times 180^\circ $$ Answer and Explanation:1 The term hendecagon comes from the Greek prefixhendeka-which means eleven an...
The sum of the interior angles of any regular polygon of n sides is equal to 180(n - 2) degrees. 1440 degrees
Polygons; Properties and Interior Angles:In geometry, polygons are defined as those planer figures that are enclosed by line segments, and at least three line segments are required to form a polygon. The polygons of three sides are known as the triangles while the polygons of...
In geometry, a trapezoid is a quadrilateral, or a two-dimensional shape with four straight sides, such that it contains one pair of opposite parallel sides. A trapezoid has four angles, and because it is a quadrilateral, we know that these angles satisfy certain properties....
To find the sum of the interior angles of a polygon, we use the angle sum theorem. This states that the sum of the interior angles will equal the number of sides minus two times 180 degrees. The formula is (# of sides - 2) X 180 degrees = sum of in...
In an equilateral triangle, what is the difference between the sum of the exterior angles and the sum of the interior angles?Angles in a Triangle:(i) The sum of all three angles in any triangle is always 180 degrees. (ii) The sum of ...
