Question

height of equilateral triangle pythagorean theorem?

Answer 1

if you know the formula use it or do by pythagoras theorem 
ex :
by Pythagoras theorem 
if sides of eq. tri. is 12
hyp= 12
base= 12/2=6
and the h= 10.392....

Answer 2

Using the Pythagorean theorem

An equilateral triangle with a side of 2 has a height of √3, as the sine of 60° is √3/2.

Internal angle (degrees): 60°

Edges and vertices: 3

Symmetry group: D³
