## What makes a pentagon?

A pentagon is any polygon that has five sides and five angles. The root of the word pentagon is “penta” which comes from the Greek word for five. “Gon” comes from the Greek word for angle. So, if you put the two words together, you get “five angles,” which corresponds to how many angles are in the shape.

Does a pentagon have 5 equal sides?

An equilateral pentagon is a polygon with five sides of equal length. However, its five internal angles can take a range of sets of values, thus permitting it to form a family of pentagons.

How many sides does a pentagon have?

5
Pentagon/Number of edges
Answer- The Pentagon has 5 (five) sides. A pentagon is a five-sided polygon also known as 5-gon in geometry. 540° is the sum of internal angles of a simple pentagon. A self-intersecting pentagon is called a pentagram.

### What is a pentagon for kid?

A pentagon is a polygon with five edges. It is defined by five points, which are all on a plane. If all the edges have the same length and the angles at the corners are all 108°, the pentagon is called regular.

What are the properties of polygon?

Properties of Polygons

• The number of sides of the shape.
• The angles between the sides of the shape.
• The length of the sides of the shape.

How many vertices does a pentagon have?

Pentagon/Number of vertices

#### Why pentagon is a 2d shape?

A pentagon is a five-sided polygon (2d Shape), and it can be regular or irregular. In the case of a regular pentagon, each interior angle is equal to 108°, and each exterior angle measures 72°. It has five diagonals.

What kind of shape is a pentagon?

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….Pentagon Shape.

Can a pentagon have 4 right angles?

A familiar investigation is to find the maximum numbers of interior angles of a polygon which can be right angles. Sum of Interior Angles = 540′. Four right angles would leave 180′, which is impossible. So a pentagon has a maximum of three right angles, as shown.

## Is pentagon a plane shape?

One kind of flat shape is the polygon, also known as a plane figure, and it’s made of lines (sides) and corners where the lines connect. Plane figures are often named based on the number of sides and corners they have. A pentagon is a plane figure that has five sides and five corners.

What are 3 characteristics of a polygon?

What are the properties of a pentagon?

Regular Pentagons: The properties of regular pentagons: All sides are the same length (congruent) and all interior angles are the same size (congruent). To find the measure of the interior angles, we know that the sum of all the angles is 540 degrees (from above)…

### How many degrees are in a pentagon?

Pentagon Definition In geometry, a pentagon is a five-sided polygon with five straight sides and five interior angles that sum up to 540° 540 °. A pentagon shape is a plane figure, or flat (two-dimensional) 5-sided geometric shape. Properties of a Pentagon

A pentagon has five sides.

• A regular pentagon has no right angles ( It has interior angles each equal to 108 degrees).
• An irregular pentagon has at most three right angles,because a fourth would leave 180 degrees to be used for the final angle that is (540 degrees – 360 degrees),…
• How many shapes does a pentagon have?

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. In addition to having five sides, the sides must also form a closed shape.
