We know that equilateral triangle is a triangle in which in all sides are equal.
So, AB = BC = AC = 1
Also, in equilateral triangle, altitude and median are the same.
As AM is the median, M is the midpoint of BC,
In the figure, AM is a median as well as an altitude.
In ,
Using Pythagoras theorem:
Similarly, in ,
