Let's look at ratios to show the 'entire' shape isn't a triangle.
The smaller triangle is 5across2high
The second triangle is 8across3high
So, to make these comparable in math, we make the denominator the same, making the ratios
15/6 & 16/6.
So the key thing here is that the first image as stated before is NOT a complete triangle, as shown by the line 'test'. And yes that little simple ratio and clever arrangement is enough to make the extra 'hole' appear, the two shapes are NOT comparable at all. A slight trick on the eye, but in my head quite easy to show why the gap appears.
To put into some amusing 4x4 related terms, the ascent is steeper on one of the triangles ;)

You want a maths problem
What is the maximum stress in a horizontal 1m long rectangular cantileaver beam with a height of 40mm and width of 60mm if a 4000 newton point load is applied downwards at the unsupported end?
If the modulas of elasticity is 200x109, what is the vertical difflection of the free end?

Still noot a maths problem, that's physics :lol: care to tell us the answer anywho? I'm entrigued but I can't see many getting it to be honest :p
