If D and E are the mid points of AB and AC respectively of  Δ ABC, then the ratio of the areas of ADE and BCED IS

       

ABC is an isosceles triangle where AB = AC which is circumscribed about a circle. If P is the point where the circle touches the side BC, then which of the following is true

ABC is an isosceles triangle inscribed in a circle. If AB = AC = 12√5 and  BC = 24 cm then radius of circle is                     

A and B are the centres of two circles with radii 11 cm and 6 cm respectively. A common tangent touches these circles at P & Q respectively. If AB = 13 cm, then the length of PQ is 

Let G be the centroid of the equilateral triangle ABC of perimeter 24 cm. Then the length of AG is

Let two chords AB and AC of the larger circle touch the smaller circle having same centre at X and Y. Then XY = ?
