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).
What else can I help you with?
How many sides does a polygon have if the interior angles equal 180 degrees?
If all of the interior angles of the polygon add up to 180 degrees, then the polygon is a triangle.
Is a regular polygon a polygon with all sides congruent?
A regular polygon is a polygon with congruent sides and interior angles.
How many sides does a polygon have if the sum of its interior angles is equal to the sum of its exterior 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.
What polygon has the most obtuse angles?
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.
What is the angle of one interior angle of a 13-gon?
Anything you like. Any single interior angle of a polygon is indeterminate - the only constraint is on the sum of all the interior angles.
What is the maximum number of sides a polygon can have if each interior angle is obtuse?
Any number of sides of 5 and above because all interior angles of regular polygons in this category will have obtuse interior angles.
How many inside obtuse angles does a polygon have?
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.
What is a polygon with all interior angles congruent?
A polygon with all interior angles congruent Is known as a regular polygon.
What is a polygon with all interior angles called?
If all of its interior angles are equal then it is a regular polygon
How many sides does a polygon have with angles of 12 degrees?
Any polygon can have two interior angles of 12 degrees. No polygon can have all its interior angles of 12 degrees.
What is a polygon with all interior angles equal?
A regular polygon.
Is Each of the interior angles in a polygon are equal in measure.?
Only when it is a regular polygon that all interior angles are of equal measure
What polygon has all sides congruent but not angles?
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.
What is he sum of the angles of an obtuse triangle?
The sum of the interior angles on an Obtuse Triangle is 1800 . This is true of ALL triangles.
Do triangles have obtuse angles?
Yes, they can have obtuse angles. A triangle can have any combination of angles as long as all interior angles add up to 180*
What is the sum of all the interior angles in a polygon?
180x(N-2)(interior angle) All polygon of the sums of exterior angles is 360. (if convex)
Which shape has angles that are all greater than a right angle?
A shape with all angles greater than a right angle is called an obtuse polygon. The simplest example of such a shape is an obtuse triangle, which has one angle greater than 90 degrees. Additionally, any polygon with all angles exceeding 90 degrees, such as a convex polygon with obtuse angles, fits this description.
