Polygons with one interior angle greater than 180 degrees are known as non-convex or concave polygons. In these shapes, at least one angle "caves in" towards the interior, causing it to exceed 180 degrees. Examples of such polygons include certain types of concave quadrilaterals and hexagons. In contrast, all angles in convex polygons are less than or equal to 180 degrees.
What else can I help you with?
Which polygons are concave?
A concave polygon will always have an interior angle with a measure that is greater than 180 degrees.
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.
Which of these two regular polygons has the largest interior angle triangle or heptagon?
It is the regular 7 sided heptagon whose interior angles are greater than the regular 3 sided triangle
What are the types of polygons according to their interior angles?
Convex : all angles less than 180 degrees. Concave: at least one reflex angle (greater than 180 deg).
What to regular polygons has a larger exterior angle?
An equilateral triangle is the only polygon in which the exterior angle is larger than the interior angle. They are equal in a square and smaller in all regular polygons with more sides,
Which polygons are concave?
A concave polygon will always have an interior angle with a measure that is greater than 180 degrees.
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.
A concave polygon has at least dent in it?
A concave polygon is a polygon with at least one interior angle greater than 180 degrees. This causes the polygon to have at least one "dent" or indentation in its shape. The presence of these interior angles greater than 180 degrees distinguishes concave polygons from convex polygons, which have all interior angles less than 180 degrees.
Which of these two regular polygons has the largest interior angle triangle or heptagon?
It is the regular 7 sided heptagon whose interior angles are greater than the regular 3 sided triangle
What are the types of polygons according to their interior angles?
Convex : all angles less than 180 degrees. Concave: at least one reflex angle (greater than 180 deg).
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 to regular polygons has a larger exterior angle?
An equilateral triangle is the only polygon in which the exterior angle is larger than the interior angle. They are equal in a square and smaller in all regular polygons with more sides,
Is a concave polygon is regular?
By definition a regular polygon cannot be concave. Concave polygons contain one or more interior angles that are greater than 180 degrees, and regular polygons can never have an interior degree greater than 180 degrees.
How many interior angles does a polygon have?
There are as many interior and exterior angles as there are sides (the line segments that make up the polygon. The sum of each pair of exterior angle and interior angle is 180 degrees, i.e. they are supplementary. For concave polygons, there will be at least one "negative" exterior angle paired with an interior angle of greater than 180 degrees - the total of the angles is still 180 degrees.
How much greater is the measure of an interior angle than an exterior angle of a regular pentagon?
The sum of interior and exterior angle = 180. The interior angle of a regular pentagon = (n-2)x180 / n = (5-2)x180/5 = 108 The exterior angle = 180 - 108 = 72 The interior angle is 35 degrees greater than exterior angle.
What is the number of sides of a regular polygon where each interior angle is 140 degree greater than each interior angle?
18
Do some polygons have a greater number of angles than sides?
No. Because to have an angle you must have adjoining sides.
