The sum of the five interior angles of ANY pentagon is 540 degrees.
If the pentagon is regular, then each angle is 108 degrees.
A pentagon is a plane area which is enclosed by five straight lines. It is, therefore, a polygon. The sum of the five interior angles of a pentagon sum to 540 degrees and so, each interior angle of a regular pentagon measures 108 degrees. A pentagon has five diagonals. It can have none of five axes of symmetry.
The formula for the internal angles of a polygon of n sides is (n-2)*180, so the sum of the angles in a pentagon is 540 degrees. For a regular pentagon, each angle would be 108 degrees.
The sum of the interior angles in a pentagon is (5-2)180 degrees or 3x180 degrees=540. Since it is regular each angle has the same measure and so each is 540/5=108 degrees.
Since the interior angle measure of the regular polygon is 140⁰, its exterior angle measure is 180⁰ - 140⁰ = 40⁰. Since the sum of the exterior angle measures is 360⁰, the polygon has 360⁰/40⁰ = 9 sides.
The sum of the interior angles of an n-gon is 180*(n-2) degrees. Whether the n-gon is regular does not matter. For a pentagon, n= 5 so the sum of the interior angles is 180*(5-2) = 540 degrees.
It's 540 degrees for any pentagon, regular or not.
For a regular polygon with sides n, the sum of the interior angles = (n-2)180Therefore, a regular polygon has interior angle sum equal to 540o.(5-2)180=(3)180=540
Each exterior angle measures 72 degrees and they add up to 360 degrees Each interior angle measures 108 degrees and they add up to 540 degrees
Each interior angle measures 108 degrees and the 5 angles of the regular pentagon add up to 540 degrees
540 degrees
the angle sum of a pentagon is 540.
to find the entire angle sum of a pentagon you would have to subtract 2 from 5, because 5 is the number of sides. You then take 3 and multiply it by 180. if it is a regular pentagon you just simply divide 540 by 5 (the number of angles) and that is the measure of each angle in the pentagon. If it isn't a regular pentagon you subtract the 3 angle measures you know from 540 and then with the remaining number you use thereoms and postulates and stuff to find the angle measures
180
The measurement of an interior angle of a pentagon depends on whether the pentagon is a "regular pentagon". The sum of the measures of the interior angles of any polygon can be calculated using the formula (n-2)180, where n = the number of sides. If the pentagon is a regular pentagon, then all of the interior angles are congruent (i.e. : 144 degrees). Interior angle is the inside angle of any angular object. A triangle for instance has three outside angles and three interior angles, the angles of the points from the inside.
A pentagon is a plane area which is enclosed by five straight lines. It is, therefore, a polygon. The sum of the five interior angles of a pentagon sum to 540 degrees and so, each interior angle of a regular pentagon measures 108 degrees. A pentagon has five diagonals. It can have none of five axes of symmetry.
If the pentagon is regular all you need do is divide 540 by 5. If it isn't regular, we can't help.
