Just use 3 of those matches or sticks to arrange into a number ' 4 ' and use the 3 left to arrange into an equilateral triangle. Put them next to each other and you'll have ''4 equilateral triangles'' from 6 equal length sticks or matches.
 
Every question of this type has its own logic. There is no fixed procedure.
