Bhuvnesh has drawn an angle of measure 45⁰7’ when he was asked to draw an angle of 45⁰. The percentage error in his drawing is 

The in-radius of an equilateral triangle is of length 3 cm. Then the length of each of its medians is 

The distance between the center of two equal circles each of radius 3 cm, is 10 cm. The length of a transverse common tangent is 

G is the centroid of ΔABC. The medians AD and BE intersect at right angles. If the lengths of AD and BE are 9 cm and 12 cm respectively; then the length of AB (in cm) is?

If ∆ABC is an isosceles triangle with ∠C = 90° and AC = 5 cm then AB is : 

Diagonals of a Trapezium ABCD with AB‖CD intersect each other at the point O. If AB=2CD, then the ratio of the areas of ΔAOB and ΔCOD is

The diagonals AC and BD of a cyclic quadrilateral ABCD intersect each other at the point P. Then, it is always true that 

D and E are midpoints of side AB and AC respectively of the ΔABC. A line drawn from A meets BC at H and DE at K. AK : KH = ?
