For a pentagon, which has 5 sides, you can use the formula:
Total Sum of Interior Angles = (5 - 2) * 180 degrees
Total Sum of Interior Angles = 3 * 180 degrees
Total Sum of Interior Angles = 540 degrees
So, the total sum of the interior angles in a pentagon is 540 degrees.
5 exterior angles add up to 360 degrees
5 interior angles add up to 540 degrees
Angles inside a hexagon = 6 Angles inside a pentagon = 5 Total = 11
Total sum of interior angles of a pentagon: 540 degrees
The triangle has three exterior angles. Added together, their total is 180 degrees.(Same as the total of the three interior angles when they're added together.)
I'm pretty sure it is 360 degrees for the whole pentagon.
A pentagon has five sides and angles, and an octagon has eight sides and angles. Together this adds up to a total of 13 angles. One trick to remember how many angles and sides a polygon has is to look at the Latin roots. For example penta- is a prefix meaning five and octa- is a prefix signifying eight.

A pentagon has 5 sides and 5 angles. The five angles add to a total of 540°. In a regular pentagon, each angle is 108°. A hexagon has 6 sides and 6 angles. The six angles add to a total of 720°. Each angle of a regular hexagon is 120°.

The internal angles of a triangle can be added together to make 180 degrees in total.
The total of the interior angles of a pentagon = 540 (in a regular pentagon, each interior angle is 108 degrees). The exterior angles would then be 5*(360-108) = 5*252 = 1260 degrees.
The inside angles total 180 degrees, and the outside angles total 360 degrees. It is the same for triangles, parallelograms, rectangles, squares, trapezoids, hexagons, heptagons, octagons, and all enclosed plane figures.
360o A pentagon is constructed of line segments or of angles. Either of those will do the job. But no matter how many degrees you have, you can't build a pentagon from them. After your pentagon is constructed, it's possible to measure the angles inside it. Those measurements will always add up to a total of 540 degrees.
The sum of the exterior angles of any polygon is 360 degrees.
