Interior angle of and 18 sided shape?
Exterior angle + interior angle = 180 Hence Interior Angle = 180 - Exterior Angle The Exterior Angle = n(No. of sides ) / 360 Substituting Interior Angle = 180 - (n/360) Interior Angle = 180 - (18/360) Interior Angle = 180 - (1/20) Interior Angle = 179.95 degrees.
What is the measure of an angle of a regular 20-sided polygon?
The interior angles of an n-sided polygon add to (n-2)*180 degrees. So the interior angles of a 20-gon add to 18*180 = 3240 degrees. The 20-gon is regular so each angle is a 20th of this ie 3240/20 = 162 deg.
What is the interior angle of a twenty sided polygon?
A twenty-sided polygon is called an "icosagon" If it is a regular icosagon - all its sides and angles are equal - then it's interior angles are all 162 degrees. You can verify this by drawing a line to the centre from each angle.. There will be 20 small angles arranged in a circle around the centre. These must total 360 degrees. As 360 / 20 = 18, this leaves the other angles of each triangle to add up to 162, because the interior angles of a triangle total 180 degrees.
What shape has a exterior angle of 20 degrees?
A regular 18 sided polygon has 18 exterior angles each measuring 20 degrees
Each exterior angle of a regular polygon measures 18 How many sides does the polygon have?
20
What is the measure of each interior angle of a 18 sided regular polygon?
The interior angle of an octdecagon, an 18 sided regular polygon, is 160o.
Interior angle of 18 sided shape?
The interior angles of an 18 sided polygon add up to 2880 degrees
How many degrees of each interior angle of a 18 polygon?
Providing that it is a regular 18 sided polygon each interior angle measures 160 degrees.
What is the measure of each interior angle of a 13 sided polygon?
Providing that it's a regular polygon each interior angle is: 1520 18' 27.69''
What is the sum of the interior angle measures of a 18-sided polygon?
2880 degrees
What is the measure of one interior angle of a regular 18-sided polygon?
Each interior angle measures 160 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°
Each interior angle on a polygon is 160 how many sides are there?
It wil be a regular 18 sided polgon
What are the interior and exterior angles of a regular 18 sided polygon?
The measure of an interior angle in degrees of a regular polygon of n sides is given by the formula: 180 x (n-2) / nSubstituting with n=18, then the answer is that the interior angle = 160The measure of an exterior angle in degrees of a regular polygon of n sides is given by the formula: 360/nSubstituting with n= 18, then the answer is that the exterior angle = 20
What is the size of each exterior angle of a regular twenty sided polygon?
You simply do 360/20=18 so the size of each interior angle is 18 degrees.
What polygon has 6660 interior angles?
A 39 sided polygon
What is the sum of the interior angle measurement of a 20 sided polygon?
The sum of the interior angles of an n-gon is (n-2)*180 degrees So for a 20 sided polygon, the sum is 18*180 = 3240 degrees. Alternatively, the sum is 18*pi radians.
