heres a way to show that the perpendicular line must half the agle of an equlilateral triangle

start with some equilateral triangle

now we know we have same length on top, we invert this same triangle reflect it down

but now this means |dw:1444024618655:dw|

so these 2 triangle u from with the perpendiculars have cut the triangle in halves

then that means these are congruent triangles threfore the 60 degree must have been split into 2, 30 degree angles up at the top
