What is interior angles?
The angles between adjacent sides of a polygon that are interior to the polygon. If the polygon is convex, the interior angles are always less than 180 degrees. If it is concave, at least one interior angle will be greater than 180 degrees.
What are the characteristics of polygons?
A polygon is any plane figure bounded only by straight lines. A triangle is therefore a polygon with three sides and a pentagon is a polygon with five sides. A convex polygon has no interior angle greater than 180° . A re-entrant polygon has at least one interior angle greater than 180° . A regular polygon has all its sides and angles equal. The sum of the interior angles of a polygon is 2n - 4 right angles (n is the number of sides). The sum of the exterior angles of a convex polygon is 360° .
How many dents does a concave polygon have?
A polygon that has one or more interior angles greater than 180° is called concave. So it has at least one, but may have more.
Does a dodecagon have obtuse angles?
Yes. Any polygon with more than four sides MUST have at least one obtuse angle.
What is a polygon that has no interior angles greater than 180 degrees?
A convex polygon.
What polygon doesn't have at least one interior angle that is right or obtuse?
The answer to this would be any acute polygon, such as an equilateral triangle. The definition of acute polygons is that no angle in the polygon is greater than or equal to 90 degrees.
What is a concave m polygon?
A concave m polygon is a 2-dimensional shape which is bounded by m straight sides with at least one internal angle that is a reflex angle (greater than 180 deg).
How are convex polygons different from concave polygons?
A concave polygon has at least one interior angle greater than 180 degrees. A convex polygon has none of those.
What is interior angles?
The angles between adjacent sides of a polygon that are interior to the polygon. If the polygon is convex, the interior angles are always less than 180 degrees. If it is concave, at least one interior angle will be greater than 180 degrees.
Differentiate convex and non convex polygon?
A convex polygon is one with no angle greater than 180 degrees. A non-convex polygon is one that is not without such an angle.
A 3 sided polygon with 1 angle greater than 90?
It can be an obtuse triangle.
What is conclave polygon?
A conclave polygon is an object with x corners where one or more corners has an angle greater than 180 degrees.
What shape has at least one angle greater than a right angle?
It is a triangle
What is the sum of angle?
An acute angle is greater than 0 but less than 90 degrees A right angle is 90 degrees An obtuse angle is greater than 90 but less than 180 degrees A reflex angle is greater than 180 degrees Exterior angles of any polygon add up to 360 degrees
Which regular polygon has interior angles with measures greater than 130?
For the interior angle of a regular polygon to be greater than 130° then the exterior angle must be less than 50°. The exterior angles of a regular polygon total 360°. 360/50 = 7.2 ....this needs to be rounded up to the next whole number. Therefore a regular polygon with 8 or more sides has interior angles measuring 130° or greater.
What is the number of sides of a regular polygon where each interior angle is 140 degree greater than each interior angle?
18
Which polygons are concave?
A concave polygon will always have an interior angle with a measure that is greater than 180 degrees.
