If you mean a decagon then its 10 interior angles add up to 1440 degrees
The measure of the exterior angle.
a convex polygon has 6 sides . What is the sum of the measure of its interior angles?
The sum of the interior angles of a 16-gon is (16-2)*180 = 2520 degrees. The measure of each interior angle cannot be determined unless the polygon is regular.
Each interior angle measures 108 degrees
The measure of each interior angle of a fifteen sided regular polygon, a pendedecagon, is 156o.
No, the interior angles of a triangle measure 180° altogether.
Each interior angle will measure 162 degrees
The interior angles measure 360 degrees.
Each interior angle will measure 156 degrees
Only when it is a regular polygon that all interior angles are of equal measure
It will have 14 sides and each interior angle will measure 2160/14 degrees
No. The sum of the other two interior angles.
It will be an equilateral triangle and each interior angles measure 60 degrees.
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°.
It is: 180-exterior angle = interior angle
-- Measure, calculate, or somehow get the measure of each interior angle. -- Add them all up to get one number which is their sum. -- That one number is the sum of the interior angles.
The measure of the exterior angle.
