Question 2. ABCDE is a regular pentagon. Diagonal AD divides angle CDE into two parts. Find the ratio of the angle ADE to angle ADC.

Question 3. The difference between exterior angle of a n-1 sided regular polygon and exterior angle of n+2 sided regular polygon is 6 degree. What is the value of n ?

Question 4. Ratio of Interior Angle to Exterior Angle of a regular polygon is 7:2 . What is the number of sides of that regular polygon ?

Question 5. The ratio of number of sides of two regular polygons is 1:2 , ratio of measure of their interior angle is 3:4 , what are the number of sides of the two polygons ?

Question 6. A six side regular polygon i.e. Hexagon is inscribed in a circle of radius 10 cm, find the length of one side of the hexagon ?

Question 7. On a regular hexagon, six circles of equal radii are drawn, with centres at each vertex, such that each circle touches the two circle with centers at adjacent vertices. Then two concentric circles C1 and C2 are drawn touching all the six circles. What is the ratio of the areas of C1 and C2, if C1 is the smaller circle.
