I was reformatting this code in a module script but for some reason it refuses to load, why?

MY VERSION:

Server Script:

local ta
local tb

local function init()
ta, tb = require(script.Triangle)(Vector3.new(0, 0, 0), Vector3.new(10, 0, 10), Vector3.new(0, 0, 10), workspace, ta, tb)
end

init()

Module:

local Triangle do

	local ref = Instance.new('WedgePart') do
		ref.Material      = Enum.Material.SmoothPlastic
		ref.Reflectance   = 0
		ref.Transparency  = 0
		ref.Name          = ''
		ref.Anchored      = true
		ref.CanCollide    = false
		ref.CFrame        = CFrame
		ref.Size          = Vector3.new(0.25, 0.25, 0.25)
		ref.BottomSurface = Enum.SurfaceType.Smooth
		ref.TopSurface    = Enum.SurfaceType.Smooth
	end
	
	local function fromAxes(part, x, y, z)
		
		return CFrame.new(part.x, part.y, part.z, x.x, y.x, z.x, x.y, y.y, z.z, x.z, y.z, z.z)
	end
	
	
	function Triangle(a, b, c, parent, wb, wc)
		--Get the distance between each point
		local A, B, C = b - a, c - b,  c - a
		local A_Magnitude, B_Magnitude, C_Magnitude = A.magnitude, B.magnitude, C.magnitude

return Triangle

It keeps returning Requested module experienced an error while loading

This is the very reason why you should learn to script before using other people's scripts and modifying them. To answer your question:

change the first line from local Triangle do to local Triangle = {}
