Characteristics of a pentagon
What are 3 characteristics of a pentagon?
The properties of a simple pentagon (5-gon) are it must have five straight sides that meet to create five vertices, but do not self-intersect: Pentagons have five straight sides. Pentagons have five interior angles, which sum to 540° The five sides do not intersect.
Does a pentagon have 5 equal sides?
Always five! In regular pentagons, all the sides are equal in length and have equal angles. The shapes having equal angles are called equiangular.
What is special about pentagon shape?
All pentagons have five straight sides, but the sides do not have to be of equal length. A regular pentagon has five equal sides and five equal angles. In basic geometry, most problems will involve regular polygons. Each interior angle of a regular pentagon = 108 degrees.
What are the properties of a pentagon for kids?
Properties of regular pentagons:
All angles are equal. All sides are of equal length. All interior angles are 108°. All exterior angles are 72°.
What type of shape is a pentagon?
A pentagon is a geometrical shape, which has five sides and five angles. Here, “Penta” denotes five and “gon” denotes angle. The pentagon is one of the types of polygons. The sum of all the interior angles for a regular pentagon is 540 degrees.
What are the properties of polygon?
Properties of Polygons
Sum of all the interior angles of an n-sided polygon = (n – 2) × 180°. The angle measurement of each interior angle of an n-sided regular polygon = (n–2)×180°/n. The angle measurement of each exterior angle of an n-sided regular polygon = 360°/n.
What are the rules of a pentagon?
Types of Pentagon
| General Rule | |
|---|---|
| Sum of Interior Angles of a polygon = | 180 ×(n−2) degrees, where n is number of sides |
| Measure of each of the Angle (in a Regular Polygon) = | 180 degrees ×(n−2) / n, where n is the number of sides/. |
What is the definition of a pentagon for kids?
A pentagon is a type of polygon that has five sides and five angles. There are many different types of polygons, but the one thing they all have in common is they are made of five straight lines and have five angles and corners.
What is a shape with five sides called?
A pentagon is a shape with 5 sides and 5 angles.
What is a 5 sided shape called?
pentagon
A pentagon is a shape with 5 sides and 5 angles. An octagon is a shape with 8 sides and 8 angles. A trapezoid is a quadrilateral with one set of parallel sides.
What shape has 7 sides called?
heptagon
A heptagon is a seven-sided polygon. It is also sometimes called a septagon, though this usage mixes a Latin prefix sept- (derived from septua-, meaning “seven”) with the Greek suffix -gon (from gonia, meaning “angle”), and is therefore not recommended.
What are shapes with 4 sides called?
A quadrilateral is a 4 sided closed figure. These figures are quadrilaterals: A shape with four sides. The shape has one set of parallel sides and does not have any right angles.
What is the difference between a polygon and a pentagon?
Polygons can be classified as regular or irregular. Regular polygons have equal interior angle measures and equal side lengths. An irregular polygon has at least one different side length and does not have equal angle measurements. A pentagon is a shape with five straight sides and five angles.

What’s a 10 sided polygon?
A decagon is a closed shape with ten sides and ten angles. Your geometry teacher would also tell you that a decagon is a polygon.
