Homework Statement
let be ABC a generic triangle, build on each side of the triangle an equilater triangle, proof that the triangle having as vertices the centers of the equilaters triangles is equilater
Homework Equations
sum of internal angles in a triangle is 180, rules about congruency in triangles
The Attempt at a Solution
i know two ways to demontrate that a triangle is equilater, congruency of the sides or same angles, but i have no clue on how to do it, i didn t found any relation between the triangles, only some opposite angles
