How is an exterior angle of a polygon formed?
180 - interior angle = exterior angle
What is the measure of each exterior angle of a 15 sided regular polygon?
24 degrees. Here's why: The sum of the deviations from a straight line at the angles must add up to 360 degrees (full circle). In a regular polygon, each deviation is equal. So, in this case, each deviation is 360 / 15 = 24 degrees. Since the exterior angle is the supplement of the interior angle (they add up to 180), this is the exterior angle.
Exterior angle property of a triangle?
measure of exterior angle of triangle is equal to sum of interior angles. for eg. In triangle ABC, angle C is exterior angle angle A and angle B are interior angles so, C=A+B
What is the measure of one exterior angle of a decagon?
Each interior angle of a decagon is 144 degrees.An exterior angle is 180 - measure of interior angle.There exterior angle of decagon is 180-144which is equal to-36
An exterior angle of a triangle is 180 degrees.?
No.Take a look at this picture...http://www.onemathematicalcat.org/Math/Geometry_obj/graphics/summing_exterior_angles.pngThe exterior angle + the interior angle = 180 degrees180 - the interior angle = the exterior angle
