What is the size of an interior angle of a 20 sided regular polygon?
exterior angle = 360° ÷ 20 sides = 18° interior angle = 180° - exterior angle = 180° - 18° = 162°
What is the name off an 18 sided shape?
All I can tell you is that a 16 sided shape is called a Hexadecagon
A 18 sided 2D shape?
Tetrahaidecahedron
How many sides does a regular polygon have with the angle 20 degrees?
If those are exterior angles, the exterior angles of any polygon add up to 360. That would be 18 sides.
What is a 18 sided 3D shape called?
Octadecadron
What is the size of an exterior angle of a regular 20-sided shape?
The exterior angle of a regular polygon can be calculated using the formula ( \frac{360^\circ}{n} ), where ( n ) is the number of sides. For a regular 20-sided shape (icosagon), the exterior angle is ( \frac{360^\circ}{20} = 18^\circ ). Therefore, each exterior angle of a regular 20-sided shape measures 18 degrees.
Interior angle for 20 sided shape?
Exterior angle = 360/20=18 interior angle = 180 - 18 = 162 Must be regular shape
What is the exterior angle of an 20 sided shape?
If it's regular then 360/20 = 18 degrees
What shape has a exterior angle of 20 degrees?
A regular 18 sided polygon has 18 exterior angles each measuring 20 degrees
Interior angle of and 18 sided shape?
To work out the interior angle use this formula(n - 2)*180/nwhere n is the number of sidesso for an 18 sided shape it would be(18-2)*180/18 = 160.
What is the exterior angle of a regular 20 sided angle?
18 degrees
What is the interior and exterior angle of a 18 sided shape?
For an 18-sided polygon (octadecagon), the formula to calculate the interior angle is ((n-2) \times 180° / n), where (n) is the number of sides. Substituting (n = 18), the interior angle is ((18-2) \times 180° / 18 = 160°). The exterior angle can be found using the formula (360° / n), which gives (360° / 18 = 20°). Therefore, each interior angle is 160° and each exterior angle is 20°.
What is the measure of an exterior angle of a regular 18-sided polygon to the nearest tenth?
Each exterior angle will measure 360/18 = 20.0 degrees
What will be the measure of an exterior angle of a regular 18 sided polygon?
56
What is the exterior angle sum of a 18 sided ploygon?
The exterior angles add up to 360 degrees.
What is the size of an interior angle of a 20 sided regular polygon?
exterior angle = 360° ÷ 20 sides = 18° interior angle = 180° - exterior angle = 180° - 18° = 162°
What is the measure of each exterior angle of an 18 sided polygon?
20 degrees
