So n 5 and it is a pentagon. We use the formula that the sum is 180 n 2 where n is the number of sides.

### From vertex a we can draw two diagonals which separates the pentagon into three triangles.

**Polygon 540 degrees**. The sum of the internal angles of a pentagon is 540 degrees here s how to find the sum of the internal interior angles of a polygon there is a formula n 2 180 where n is the number of. To find the measure of the angles of a regular polygon simply apply the formula and divide by the number of sides. The angles in a quadrilateral a 4 sided polygon total 360 degrees.

Make sure each triangle here adds up to 180 and check that the pentagon s interior angles add up to 540 the interior angles of a pentagon add up to 540. 180n 360 540. Hexagon has 6 so we take 540 180 720.

Here s a pentagon a 5 sided polygon. Write and solve an equation to find the value of x. So if we know that a pentagon adds up to 540 degrees we can figure out how many degrees any sided polygon adds up to.

The angles in a hexagon a 6 sided polygon total 720 degrees. Some common polygon total angle measures are as follows. A pentagon has five sides so the sum of its angles is equal to 180 5 2 or 540 degrees.

180n 540 360. For example 540 divided by 5 is 108 so the angles of a regular pentagon must each measure 108 degrees. 5 sides 0 0 1.

So 540 180 n 2 540 180 n 2. The angles in a triangle a 3 sided polygon total 180 degrees. This formula works for both regular and irregular polygons no matter how many sides are involved.

The sum of the angle measures of the polygon is 540. And when it is regular all angles the same then each angle is 540 5 108 exercise. Sum of angles n 2 180.

A heptagon has 7 sides so we take the hexagon s sum of interior angles and add 180 to it getting us 720 180 900 degrees. We multiply 3 times 180 degrees to find the sum of all the interior angles of a pentagon which is 540 degrees. The angles in a pentagon a 5 sided polygon total 540 degrees.

Use the theorem that says that if n is the number of sides of a polygon the sum of the interior angles is n 2 180.
