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.
