did u count properly? Green color occupues the same number of boxes..unless i didnt do math in my high skool
Good puzzle. I'm struggling unless it's some sort of optical illusion with the grid lines - do they converge towards the top?
Yes, it's an illusion. I guess the squares in the grid become larger at the bottom so the shapes are basically a lot different in size. Going to check with my ruler later
its just that the colored parts are moved around..i am thinking..but dont know..whether its an optical illusion or something else
The red and green triangles are not similar. The red triangle has perpendicular sides of 3 and 8. The green triangle has perpendicular sides of 2 and 5. Both has different angle measurements. The diagram itself is incorrect. The combined figure will not be a triangle but a polygon with four sides. That's why the extra square is visible in the second figure.
i was pathetically poor in even higher math, Integration..calculus etc..so cant confirm what you said
Sachin is right. For the figure to be true, angle 1 and angle 2 must be equal. (see the figure below). And both the angles will be equal iff 3/8 = 2/5 which is not true. So I think the figure is wrong.
i dont understand math by numbers.. what i do understand is laymens language....lol after much engrossing myself into thinking more and more..i noticed this..and this is a lot easier to understand..the Angles of the triangle Green and Red are not the same in both the pictures..they are actually more elongated
i know this puzzle from a psychology book,i recognized the picture immediately but i'm to lazy to search for it right now because of the heat
It is an optical illusion then - the 'point' angle in the red triangle is 20.56 degrees, whereas in the green triangle it's 21.80 degrees - a very subtle difference barely noticeable to the eye.
Everyone is focusing on the wrong thing, I think, aren't they? The angle is slightly different in those triangles - more perceivable in the smaller image, than the large one, but who cares? Its just a game of tetris. The pieces are just arranged different, so there is now a gap in there.
Exactly. I just made a rough diagram for it. The two angles A and B are unequal and thus the figures are not triangles but four sided polygons. I deliberately exaggerated the angles in the figures, to make difference more clear.
