Question

An equilateral triangle lies completely in the first quadrant of certain frame of reference .two of its vertices have coordninates (3,2)and (5,3)find co ordinate ofthird vertex

Answer 1

find the length of the 3 sides by keeping the 3rd coordinate as (x,y) and keep these lengths equal and you will get 2 equation by which you can find the length of x and y and hence the 3rd co-ordinate
