A right angle is not 125
Exterior angle measures 18 degrees Interior angle measures 162 degrees
To solve for the exterior angle of a triangle, use the Exterior Angle Theorem, which states that the measure of an exterior angle is equal to the sum of the measures of the two non-adjacent interior angles. To apply this, identify the exterior angle and the two corresponding interior angles. Simply add the measures of those two interior angles together to find the value of the exterior angle. For example, if the interior angles are 40° and 60°, the exterior angle would be 40° + 60° = 100°.
Subtract the interior angle by 360 degrees
If exterior angles are 120 then interior angles must be 60 so you have an equilateral triangle
Providing that it is a regular hexagon then the each interior angle measures 120 degrees and each exterior angle measures 60 degrees
Exterior angle measures 18 degrees Interior angle measures 162 degrees
Subtract the interior angle by 360 degrees
180
The total of the interior angles equal 5040, and each angle measures 168 degrees The total of the exterior angles equal 360, and each angle measures 12 degrees
If exterior angles are 120 then interior angles must be 60 so you have an equilateral triangle
Providing that it is a regular hexagon then the each interior angle measures 120 degrees and each exterior angle measures 60 degrees
360
Exterior angle.
Exterior angle+interior angle=180 degrees and 180-exterior angle=interior angle
540 degrees
Each interior angle is 108 degrees and its 5 angles add up to 540 degrees
two opposite interior angles.
