isogon: 20 sides proof: 180(n-2)/n 180(18)/20 3,240/20 162 Thus, each angle is 162 degrees, which is greater that 90 making it obtuse.
Any number of sides of 5 and above because all interior angles of regular polygons in this category will have obtuse interior angles.
Yes a regular pentagon has five interior angles of 108 degrees
A hexagon has six angles. A regular hexagon has six angles and each one is equal in measure to 120 degrees. 120 degrees is an obtuse angle. Any regular polygon with at least 6 sides has at least 6 obtuse angles.
An obtuse angle is an angle that is greater than 90 degrees but less than 180 degrees. The internal angles of any regular polygon with 5 or more sides will be obtuse.
Oh, what a happy little question! In a star shape, each point creates an angle. If we connect those points, we can see that each angle is less than 90 degrees, so there are no obtuse angles in a star. Just think of all those lovely acute angles coming together to make a beautiful star!
Any number of sides of 5 and above because all interior angles of regular polygons in this category will have obtuse interior angles.
A regular octagon has 8 interior obtuse angles.
Obtuse
triangel
In a regular hexagon there are 6 obtuse interior angles.

octagon, trapezoid, pentagon...* * * * *Not true.A trapezium (or trapeziod) must have at least one acute angle.Any regular polygon with 5 or more sides has all obtuse angles. However, an irregular polygon can always have one or more non-obtuse angles (acute, right or even reflex).
A regular polygon of n sides (where n > 4) has n obtuse angles. Since there is no limit to the number of sides that a polygon can have, there can be no limit to the number of obtuse angles in a shape.
Yes the interior angles of a regular octagon are obtuse.
An obtuse triangle has 3 sides.
The number of inside obtuse angles in a polygon can vary depending on the specific type and shape of the polygon. However, a polygon can have multiple obtuse angles as long as the sum of the interior angles remains consistent with the formula ( (n - 2) \times 180^\circ ), where ( n ) is the number of sides. For example, a polygon could have 2, 3, or more obtuse angles, as long as the total angle measure is maintained. Thus, there is no fixed number of obtuse angles for all polygons.
Yes a regular 8 sided octagon has 8 interior obtuse angles of 135 degrees.
