## Are all the sides of a regular Pentagon equal?

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)…

And there are five angles…

So, the measure of the interior angle of a regular pentagon is 108 degrees..

## Are all sides equal in a polygon?

In Euclidean geometry, a regular polygon is a polygon that is equiangular (all angles are equal in measure) and equilateral (all sides have the same length). Regular polygons may be either convex or star.

## What is a 5 sided shape called?

pentagonMore than Four Sides A five-sided shape is called a pentagon. A six-sided shape is a hexagon, a seven-sided shape a heptagon, while an octagon has eight sides…

## What is a 10 sided shape called?

decagonIn geometry, a decagon is a ten-sided polygon or 10-gon.

## Does a Pentagon have a 90 degree angle?

1 Answer. There are no right angles among interior angles of a regular pentagon.

## What is the difference between a pentagon and a regular pentagon?

Pentagons can be regular or irregular and convex or concave. A regular pentagon is one with all equal sides and angles. Its interior angles are 108 degrees and its exterior angles are 72 degrees. An irregular pentagon is a shape that does not have equal sides and/or angles and therefore do not have specified angles.

## What is a 9 sided shape called?

enneagonIn geometry, a nonagon (/ˈnɒnəɡɒn/) or enneagon (/ˈɛniəɡɒn/) is a nine-sided polygon or 9-gon. The name nonagon is a prefix hybrid formation, from Latin (nonus, “ninth” + gonon), used equivalently, attested already in the 16th century in French nonogone and in English from the 17th century.

## What is a 200 sided shape?

Self. Properties. Convex, cyclic, equilateral, isogonal, isotoxal. In geometry, a hectogon or hecatontagon or 100-gon is a hundred-sided polygon. The sum of all hectogon’s interior angles are 17640 degrees.

## What is a 8 sided shape called?

octagonIn geometry, an octagon (from the Greek ὀκτάγωνον oktágōnon, “eight angles”) is an eight-sided polygon or 8-gon. A regular octagon has Schläfli symbol {8} and can also be constructed as a quasiregular truncated square, t{4}, which alternates two types of edges. A truncated octagon, t{8} is a hexadecagon, {16}.

## Does a Pentagon have 4 equal sides?

A regular pentagon has all equal sides and angles. In a regular pentagon, its interior angles are 108 degrees and its exterior angles are 72 degrees. The angles of a pentagon add up to 540 degrees.

## Can a shape have 2 sides?

In geometry, a digon is a polygon with two sides (edges) and two vertices. … A regular digon has both angles equal and both sides equal and is represented by Schläfli symbol {2}.

## What’s a 13 sided shape called?

tridecagonIn geometry, a tridecagon or triskaidecagon or 13-gon is a thirteen-sided polygon.

## What is 12 sided shape called?

dodecagonIn geometry, a dodecagon or 12-gon is any twelve-sided polygon.

## Is any 5 sided shape called a pentagon?

In geometry, a pentagon (from the Greek πέντε pente and γωνία gonia, meaning five and angle) is any five-sided polygon or 5-gon. The sum of the internal angles in a simple pentagon is 540°. … A self-intersecting regular pentagon (or star pentagon) is called a pentagram.

## What is a 4 sided shape called?

A quadrilateral is a four-sided polygon with four angles. There are many kinds of quadrilaterals. The five most common types are the parallelogram, the rectangle, the square, the trapezoid, and the rhombus. Move your mouse cursor over the figures at the right to learn more.

## Does a Pentagon have 5 congruent sides?

A regular pentagon must have five congruent sides, five congruent interior angles, and congruent exterior angles: five congruent sides (sides of equal length) five congruent interior angles (each measuring 108° )

## Which has more sides a hexagon or a pentagon?

A hexagon has more sides than a pentagon. A hexagon is a polygon that has six sides and a pentagon is a polygon that has five sides.
