You don’t ever really have a triangle. The two smaller triangles have a different slope and so do not form a straight line for the hypotunuse of the triangle.
The Blue square has a slope of 2/5 or .4 and the red square has a slope of 3/8 or .375.
You just can’t see the difference.
So the premise is wrong you never have a triangle.

The less technical answer: the square is dispersed in small increments along the hypotenuse of the second “triangle”.

How can you have a different slope if the slope is a straight line and is 5 high and 13 long… If you look at the spot they reach they would have to have the same slope. from the right angle they both go to 5 and 13 squares still so to have a different slope would mean the slope would have to curve… and I mean… it looks like he cut them pretty straight
