Question

In the given figure triangle ABC and triangle ABC are equal lateral Triangles find the coordinates of the point c and d

Answer 1

Given,

ABC is equilateral triangle ,

AB = BC = CA = a+ a = 2a

InΔAOC

CO² = AC² - AO²

= (2a)² - a²

= 3a²

CO = a√3

Similarly ,

OD = a√3

Hence, co

ordinates of C = (0, OC) = ( 0, a√3 )

Coordinates of D = (0, -OD) = ( 0, -a√3 )
