The measure of the exterior angle.
It is: 180-vertex angle = exterior angle
Exterior angle+interior angle=180 degrees and 180-exterior angle=interior angle
Usually, the measure of an exterior angle of a pentagon is greater.
Each exterior angle will measure 9 degrees
180-interior angle = exterior angle
The measure of the exterior angle.
It is: 180-vertex angle = exterior angle
Exterior angle+interior angle=180 degrees and 180-exterior angle=interior angle
Usually, the measure of an exterior angle of a pentagon is greater.
Each exterior angle will measure 9 degrees
Providing that it's a regular decagon then each exterior angle will measure 36 degrees
It is: 180-exterior angle = interior angle because there are 180 degrees on a straight line
The largest exterior angle measure is 120o. It is the exterior measure of an equilateral triangle (which is a regular polygon).
With a protractor or if you know the exterior angle then it's 180 - exterior angle = interior angle
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
360/number of sides = exterior angle
