180 - interior angle = exterior angle
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.
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
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
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
The exterior angle will be: 360/8 = 45 degrees
When any side of triangle is extended outwards then exterior angle is formed. Sum of this exterior angle and adjacent interior angle = 180o. If exterior angle = 180o(straight angle) then interior adjacent angle is 0o which is not possible. So exterior angle can't be straight angle.
It is an angle less than 90 degrees.
116 degrees ( Maybe)
An interior angle and the corresponding exterior angle add up to a straight angle. that is, they are supplementary.
180 minus interior angle = exterior angle because there are 180 degrees on a straight line
It is: 180-exterior angle = interior angle because there are 180 degrees on a straight line
Extend any straight side of a shape. The angle made by that side with the adjacent side of the shape is an exterior angle. Its value is 180 degrees less the interior angle.
Interior and adjacent exterior angles form a straight line so exterior angle = 180 - interior angle. If you are satisfied with this reply please consider awarding a Recommended Point to the responder.
The measure of an exterior angle of a triangle is more than the measure of the intersection of two straight lines.
The exterior angle sum of ANY plane polygon (ie 2-dimensional figure with straight sides) is 360 degrees.
The exterior angles of any polygon add up to 360 degees so if it's a regular polygon each exterior angle is 360/number of sides. Or 180 -interior angle = exterior angle because angles on a straight line add up to 180 degrees.
