#### What is the name of a 9 sided shape?

In geometry, a**nonagon**/ˈn?n?g?n/ (or**enneagon**/ˈ?niː?g?n/) 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 shape that has 9 sides?

2D ShapesTriangle - 3 Sides Square - 4 Sides Pentagon - 5 Sides Hexagon - 6 sides Heptagon - 7 Sides Octagon - 8 Sides Nonagon - 9 Sides Decagon - 10 Sides More #### How many triangles are in a Heptagon?

A Heptagon, also known as a septagon, has 7 sides. The number of triangles that can be drawn from 1 vertex in any polygon with n sides, is n-2. Thus you can draw**5 triangle**from a single vertex of a Heptagon.

B.

### What is the angle of Heptagon?

To find the measure of the interior angles, we know that the sum of all the angles is

**900 degrees**(from above) And there are seven angles So, the measure of the interior angle of a regular heptagon is about**128.57 degrees**.#### Do all quadrilaterals have 360 degrees?

The**Quadrilateral**Sum Conjecture tells us the sum of the angles in any convex**quadrilateral is 360 degrees**. Remember that a polygon**is**convex if each of its interior angles**is**less that 180**degree**.#### Is a hexagon regular or irregular?

A**hexagon**is an example of a**polygon**, or a shape with many sides. A**regular hexagon**has six sides that are all congruent, or equal in measurement. A**regular hexagon**is convex, meaning that the points of the**hexagon**all point outward. All of the angles of a**regular hexagon**are congruent and measure 120 degrees.#### What is the sum of the exterior angles of a Heptagon?

To find the measure of the interior angles, we know that the sum of all the angles is 900**degrees**(from above) And there are seven angles So, the measure of the interior angle of a regular heptagon is about 128.57**degrees**.

C.

### What is the shape of a Heptagon?

A

**polygon**is an enclosed two-dimensional shape with**straight**sides. This includes triangles, quadrilaterals, pentagons, etc but not circles or ovals. A heptagon is a seven-sided**polygon**. Along with seven sides, a heptagon has seven vertices and angles.#### Are all 4 sided shapes are parallelograms?

A**parallelogram**is a**four**-**sided shape**with opposite**sides**that are**parallel**. Because**of the parallel**lines,**the**opposites**sides**are equal in length. There are some unique properties**of the**angles inside**parallelograms**. First,**the**opposite angles are equal.#### What is the shape of a hexagon?

Shapes for kids: Hexagons. The hexagon is a six sided**polygon**. Each side must be closed and the shape not only needs six sides to qualify as a hexagon, but it must have six angles.#### Is a hexagon regular or irregular?

A**hexagon**is an example of a**polygon**, or a shape with many sides. A**regular hexagon**has six sides that are all congruent, or equal in measurement. A**regular hexagon**is convex, meaning that the points of the**hexagon**all point outward. All of the angles of a**regular hexagon**are congruent and measure 120 degrees.
