 # What Polygon Has All Obtuse Angles?

## How many obtuse angles has a hexagon?

six obtuse anglesA hexagon has six obtuse angles.

Every hexagon is made up of six angles of 120o .

An obtuse angle is any angle greater than….

## What is a polygon with all obtuse angles?

Since an obtuse is any angle greater than 90∘ but less than 180∘ , this means that 108∘ must be an obtuse angle. Since there are 5 108∘ angles in a pentagon, then there are 5 obtuse angles in a regular pentagon.

## Does a hexagon have all obtuse angles?

Every regular hexagon has six interior angles of 120-degrees. By definition, an obtuse angle is any angle greater than 90 and less than 180 degrees. Thus, any regular hexagon fulfills your criteria.

## 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 6 sided shape called?

hexagonMore 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 are the 7 types of angles?

The different types of angles based on their measurements are: Acute Angle – An angle less than 90 degrees. Right Angle – An angle that is exactly 90 degrees….Types of Angles – Acute, Right, Obtuse, Straight and Reflex…Acute angle.Right angle.Obtuse angle.Straight angle.Reflex angle.

## Can two obtuse angles be supplementary?

No, two obtuse angles cannot be supplementary angles. Obtuse angles are angles that have a measure greater than 90°.

## Can a triangle have two right angles?

Answer and Explanation: Because of the fact that the sum of the three interior angles of a triangle must be 180 degrees, a triangle could not have two right angles.

## Do polygons have obtuse angles?

In geometry, we are learning about angles! Any angle greater than a right is called an obtuse angle. … We have also learned that polygons are closed plane figures with straight sides and that all polygons have angles!

## What shapes have obtuse angles?

## What is the angle of obtuse angle?

An obtuse angle …” A 190 degree angle is not obtuse. An obtuse angle has a measurement greater than 90 degrees but less than 180 degrees. However, A reflex angle measures more than 180 degrees but less than 360 degrees.
