What is a simple definition of a pentagon?
: a polygon of five angles and five sides.
How do you describe a pentagon?
In geometry, a pentagon is a five-sided polygon with five straight sides and five interior angles that sum up to 540° . A pentagon shape is a plane figure, or flat (two-dimensional) 5-sided geometric shape.
What is a pentagon Grade 3?
A pentagon is a polygon with 5 sides and 5 angles. The word “pentagon” is made up of two words, namely Penta and Gonia, which means five angles. All the sides of a pentagon meet with each other end to end to form a shape. Therefore, The number of sides of a pentagon = 5.
What is pentagon shape in the home?
Toy houses are yet another example of pentagon shape in real life. If you look closely at a playhouse or a dog house, the outer boundary generally consists of five sides, five corners, and five angles.
What is the meaning of a pentagon shape?
A pentagon shape is a flat shape or a flat (two-dimensional) 5-sided geometric shape. In geometry, it is considered as a is a five-sided polygon with five straight sides and five interior angles, which add up to 540°. Pentagons can be simple or self-intersecting.
What is pentagon polygon?
In geometry, a pentagon (from the Greek πέντε pente meaning five and γωνία gonia meaning angle) is any five-sided polygon or 5-gon. The sum of the internal angles in a simple pentagon is 540°. A pentagon may be simple or self-intersecting. A self-intersecting regular pentagon (or star pentagon) is called a pentagram.
What does pentagon shape mean?
What is pentagon and example?
A pentagon is a two-dimensional geometric figure that consists of five sides and five angles. Pentagon shape falls under the category of polygons, which means the shapes that consist of more than two sides. Examples of Pentagon. 1. Buildings.
Why is the Pentagon 5 sides?
Why is the Pentagon, you know, a pentagon? The land the Pentagon was first planned to go on was bordered on five sides by roads, so the architects designed a five-sided building.
What is the difference between a polygon and a pentagon?

What is an example of a Pentagon in real life?
The definition of a pentagon is a figure with five straight sides and five angles, or a building near Washington D.C. that serves as the headquarters of the Department of Defense. The five-sided shape of a road sign used for school advance warning signs is an example of a pentagon.
Is a Pentagon a regular or irregular shape?
A pentagon is a 5-sided Polygon (a flat shape with straight sides): When all angles are equal and all sides are equal it is regular, otherwise it is irregular: A convex pentagon has no angles pointing inwards. More precisely, no internal angles can be more than 180°.
What is the formula for a pentagon?
If you are given its length, you can use this easy formula Area of a regular pentagon = pa/2, where p = the perimeter and a = the apothem. If you don’t know the perimeter, calculate it from the side length: p = 5s, where s is the side length.
