Question

In the given regular hexagon ABCDEF, find the measure of the central angle.

  1. 30    
  2. 60    
  3. 120    
  4. 135    

hintHint:

Angle is a figure which is formed when two rays meet at a common point. Angles can be of many types one of them is central angles. Central angle is formed when two radii of a circle meet at the centre the circle. Central angle of a regular polygon can be determined by using the formula fraction numerator 360 over denominator N o. space o f space s i d e s end fraction . Here, we have to find the central angle of the given regular polygon.

The correct answer is: 60


    In the question the there is a regular polygon as shown in the figure above.
    Here, we have to find the central angle of the given polygon.
    Central angle = fraction numerator 360 over denominator N o. space o f space s i d e s end fraction
    fraction numerator 360 over denominator 6 end fraction
    = 60 degree
    So, the central angle of the given polygon is 60 degree.
    Therefore, the correct option is b, i.e., 60 degree.
