Interior and Exterior Angles Definitions & Formulas with Examples
The word "polygon" means "many-sided figure." A polygon has the same number of angles as it has sides, and a regular polygon has equal angles and equal sides. Any polygon can be divided into triangles.

Angles in polygons relate to the interior and exterior angles of regular and irregular polygons. Interior angles are the angles within a polygon made by two sides. We can calculate the sum of the interior angles of a polygon by subtracting 2 from the number of sides and then multiplying by 180º. Step-by-step guide: Interior angles of a polygon

Example 1: Find the interior angle at vertex B in the following figure. Solution: The number of sides of the given polygon is n =6, so it's a hexagon (Hexagon has 6 sides). Thus, the sum of the interior angles of this polygon is 180(n-2)º. = 180(6-2) = 180 × 4 = 720° We know that the sum of all the interior angles in this polygon is equal to.

Scroll down the page for more examples and solutions on the interior angles of a polygon. Example: Find the sum of the interior angles of a heptagon (7-sided) Solution: Step 1: Write down the formula (n - 2) × 180°. Step 2: Plug in the values to get (7 - 2) × 180° = 5 × 180° = 900°. Answer: The sum of the interior angles of a heptagon (7.

A Regular Polygon's interior angles are defined as "180 0 (n) - 360 0" / n. Method 2: To calculate the interior angle of a polygon, we take the exterior angle as an input and then apply the following formula. Observe that the interior angle of a polygon is equal to 180 0 minus the exterior angle of the polygon. Method 3:

PPT Finding the Measure of Angles in Polygons PowerPoint Presentation
Let us discuss the three different formulas in detail. Method 1: If "n" is the number of sides of a polygon, then the formula is given below: Interior angles of a Regular Polygon = [180° (n) - 360°] / n. Method 2: If the exterior angle of a polygon is given, then the formula to find the interior angle is.

For example, for a hexagon you should draw three lines, dividing the shape into 4 triangles. 4. Multiply the number of triangles you created by 180. Since there are 180 degrees in a triangle, by multiplying the number of triangles in your polygon by 180, you can find the sum of the interior angles of your polygon. [8]

About. Transcript. To find the interior angle sum of a polygon, we can use a formula: interior angle sum = (n - 2) x 180°, where n is the number of sides. For example, a pentagon has 5 sides, so its interior angle sum is (5 - 2) x 180° = 3 x 180° = 540°. Created by Sal Khan.

Pentagon. A pentagon has 5 sides, and can be made from three triangles, so you know what. its interior angles add up to 3 × 180° = 540° And when it is regular (all angles the same), then each angle is 540° / 5 = 108° (Exercise: make sure each triangle here adds up to 180°, and check that the pentagon's interior angles add up to 540°)

The number of sides of the given polygon is n = 23. By interior angle formula, The sum of interior angles = 180 (n-2)º= 180 (23-2)º. = 180 (21) º. = 3780º. The measure of each interior angle is obtained by dividing the above sum by 23. Each interior angle = 3780 / 23 = 164.35°. Answer: Each interior angle of a polygon of 23 sides = 164.35°.
