A pentagon: 5 sides.
triangel
5
An obtuse triangle has 3 sides.
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.
5 or more
The internal angles of a regular nonagon (a polygon having 9 sides) are obtuse angles of 140o.
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.
Obtuse 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).
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.
Any number of sides of 5 and above because all interior angles of regular polygons in this category will have obtuse interior angles.
