Interior angle for 20 sided shape?
Exterior angle = 360/20=18 interior angle = 180 - 18 = 162 Must be regular shape
What is the measure of an exterior angle of a regular 20- sided polygon?
360/20 = 18 degrees.
What is the exterior angle of a twenty sided ploygon?
The sum of the exterior angles of a polygon, however many sides it has, is 360 degrees. If the 20 sided polygon is regular, its angles are equal, and each is then 360/20 = 18 degrees.
What is the interior and exterior angles on a 20 sided shape?
Interior angles total 40 - 4 right angles, ie 36 x 90o, so each interior angle is 18 x 9 ie 162o and the exterior is 180 - 162 = 18o
What is the sum of the interior angle measured by a 20-sided polygon?
162o. Method 1: Sum of interior angles of n-sided polygon = (2n - 4) right angles. In this case n = 20 so total of interior angles is 36 x 90o. Assuming polygon is regular then each interior angle is (36 x 90) divided by 20 = 3240/20 = 162. Method 2: Exterior angles of regular n-sided polygon = 360/n which in this case = 360/20 =18. Straight line is 180o so interior angle = (180 - exterior angle) = 180 - 18 = 162.
What is the exterior angle of an 18 sided shape?
The exterior angle of a 18 sided shape is 360/18 =20 degrees The exterior angle is always 360 divided by the numbe of sides of that polygon. =) what the hell im i doing answering this?
Interior angle for 20 sided shape?
Exterior angle = 360/20=18 interior angle = 180 - 18 = 162 Must be regular shape
What shape has a exterior angle of 20 degrees?
A regular 18 sided polygon has 18 exterior angles each measuring 20 degrees
What is the exterior angle of a regular 20 sided angle?
18 degrees
What is the exterior angle of a 18 sided polygon?
each angle= 20 degree
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
What is the measure of each exterior angle of regular 18 sided polygon?
20
What is the measure of an exterior angle of a regular 20- sided polygon?
360/20 = 18 degrees.
What is the measure of each exterior angle of a regular 18- sided polygon?
20
What is the exterior angle of a regular 18 sided polygon?
20 degrees. The exterior angles always add up to 360 degrees.
What is the exterior angle of a twenty sided ploygon?
The sum of the exterior angles of a polygon, however many sides it has, is 360 degrees. If the 20 sided polygon is regular, its angles are equal, and each is then 360/20 = 18 degrees.
