## Rizaldo 4 years ago Is it really a defect in formula or what's actually going on ? Please comment on the figure contents!

Those were more mind bloggling, bt this one is different as when you calculate the area of the figures in side the triangle it results different from when you calculate the area for big or whole triangle.

I assumed it is just a variation of the theme. Is it serious question or just puzzle?

its the same concept. The slope of the red triangles hypotenuse is 3/8 The slope of the green triangles hypotenuse is 2/5. That long "hypotenuse" isnt a hypotenuse at all. Its bent.

its really a quadrilateral that looks like a triangle (because of the small bend)

how come it be a quadrilateral, I don't think so. Althou I don't hav any clue, bt you can check this happens when you do it by yourself.

if you have a right triangle, the hypotenuse has to the the same slope the whole way through. it cant bend. but like i said earlier, the red triangles hypotenuse has a different slope than the green one. Calculating the area piece by piece is the correct way. Treating the whole thing like a triangle isnt, because its not a triangle. Just because it looks like one doesnt mean it is. Thats where the trick lies.

2/5 doesnt equal 3/8

Well I am willy-nilly agree w/u. ;)
