Consider a right triangle. One of the exterior angles 90 degrees.
It is: 180-exterior angle = interior angle because there are 180 degrees on a straight line
In a regular polygon, the measure of the exterior angle is related to the interior angle by the equation: exterior angle = 180° - interior angle. If the exterior angle is twice the measure of the interior angle, we can set up the equation: exterior angle = 2 × interior angle. Solving this gives us the equation: 180° - interior angle = 2 × interior angle, leading to 180° = 3 × interior angle, or interior angle = 60°. This corresponds to a regular hexagon, as it has interior angles of 120° and exterior angles of 60°.
Providing that it's a regular decagon then each exterior angle will measure 36 degrees
The measure of the exterior angle of a convex octagon is indeterminate.
The sum is always 360 degrees. Note, though, that when the interior angle is convex, the measure of the exterior angle is negative.The sum is always 360 degrees. Note, though, that when the interior angle is convex, the measure of the exterior angle is negative.The sum is always 360 degrees. Note, though, that when the interior angle is convex, the measure of the exterior angle is negative.The sum is always 360 degrees. Note, though, that when the interior angle is convex, the measure of the exterior angle is negative.
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
