Equilateral triangle 
is inscribed in a circle with radius 
, what is the length of a side of the triangle?
Equilateral triangle
Tap to reveal answer
Since we are given the radius, we should be able to find the height of the equilateral triangle. Indeed, the center of the circle is at the intersections of the heights of the triangle, and is located 
away from the edge of a given height.
Therefore 5, the radius of the circle is 
of the height.
Therefore, the height must be 
.
From here, we can use the formula for the height of the equilateral triangle 
, where 
is the length of the height and 
is the length of a side of the equilateral triangle.
Therefore, 
, then 
is the final answer.
