A pentagon has five sides and five interior angles which add up to a total of 540 degrees. To determine the number of degrees of the interior angles in a pentagon requires subtracting two from the number of sides (five) and multiplying by 180.
A pentagon can have from one to three right angles but only if it is an irregular pentagon. There are no right angles in a regular pentagon.
The sum of the interior angles of a pentagon is 540 degrees. Each of the five interior angles of a regular pentagon measures 108 degrees.
The Pentagon is located in Arlington County, Va., in the United States. It is located near the national capital, Washington, D.C. The Pentagon is a large five-sided building and is home to the U.S. Department of Defense headquarters.
The Pentagon contains 6.5 million square feet situated on approximately 34 acres, including its 5-acre central courtyard. It has five stories above ground and two basement levels under ground. Its corridors run 17.5 miles. The Pentagon is the largest office building in the world.
There are examples of pentagons in real life in man-made structures like the Pentagon in the United States, and also in nature in flowers like morning glories and okra. Other items, like home plates in baseball, are often in the shape of irregular pentagons.
As of 2014, about 23,000 people work in the Pentagon. The staff at the Pentagon includes a combination of civilian and military personnel. The facility was completed in 1943 and was meant to be the hub from which the country managed issues related to World War II.
A pentagon is a two-dimensional geometric figure that has five sides. A regular pentagon is one where all five sides are the exact same length and the internal angles are all 108 degrees.
To calculate the area of a regular pentagon, the perimeter of the polygon is multiplied by the apothem and the result is divided in half. The mathematical formula for the calculation is area = (apothem x perimeter)/2.
According to the University of Washington math department, a regular pentagon has five obtuse angles. The sum of all angles for a regular pentagon is 540 degrees, making each angle 108 degrees. Any angle over 90 degrees is obtuse.
