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).
If all of the interior angles of the polygon add up to 180 degrees, then the polygon is a triangle.
A regular polygon is a polygon with congruent sides and interior angles.
The sum of the exterior angles of all polygons equals to 360⁰.Since only the sum of the interior angles of all quadrilaterals equals to 360⁰, the polygon must have 4 sides.
The more sides you add to a figure, the more obtuse angles it has, assuming all of the polygons are perfect (all angle measures =, all side lengths =). An equilateral triangle has 0 (all acute), a square has 0 (all right), a pentagon has 5 (all obtuse), a hexagon has 6, a heptagon has 7, and so on. So really, it's a polygon with an infinite number of sides, which would look like a circle.
Anything you like. Any single interior angle of a polygon is indeterminate - the only constraint is on the sum of all the interior angles.
Any number of sides of 5 and above because all interior angles of regular polygons in this category will have obtuse interior angles.
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.
A polygon with all interior angles congruent Is known as a regular polygon.
If all of its interior angles are equal then it is a regular polygon
Any polygon can have two interior angles of 12 degrees. No polygon can have all its interior angles of 12 degrees.
A regular polygon.
Only when it is a regular polygon that all interior angles are of equal measure
The sum of the interior angles on an Obtuse Triangle is 1800 . This is true of ALL triangles.
It is a rhombus that has 4 equal sides with 2 equal acute and 2 equal obtuse interior angles that add up to 360 degrees.
Yes, they can have obtuse angles. A triangle can have any combination of angles as long as all interior angles add up to 180*
180x(N-2)(interior angle) All polygon of the sums of exterior angles is 360. (if convex)
If all of the interior angles of the polygon add up to 180 degrees, then the polygon is a triangle.
