Magic Puzzle - Solution
The sides of the triangles or not equal. The red figure with a degree of 3/8 can not be fitted on the green figure with a degree of 2/5 ! The angle is 15/40 vs 16/40. That’s too small a difference for our human eyes.
(That’s why I had to let to turn the green triangle itself in the animation, if it was just moved you could notice this effect …)
Someone sent me the following explanation.
‘I think I got it, 1/40 means that for every 40 cells one 1 cell is added. The green triangle is 5 cells horizontal. That’s 1/40 * 5 = 1/8 cell difference. When this number is multiplied by the number of vertical cells of the whole figure the result is 1/8 * 8 = 1 !’
Probably using tan, sin and cos will give the right answer. It is interesting if the proposition above is valid. Well ain’t got time to check it now. You have ?
good puzzle.
very simple, the lenght of the little squares of the backgrounddoes not have the same measurement than if you measure them by a the horizontal side.
If you place a straightedge along the hypotenuse, you can see that this edge is concave in the upper figure and convex in the lower figure. This makes up for the difference of the area created by the box.
Simple. If you measure the height and length of the triangle the area will be 32.5 square units. Makes it kinda of obvious that there is a variation in the angles. It was nice to be surprised by it though.
u idiots! this is so simple, a fifth grader could figure it out! jeez! i mean really! come on! its not that complicated. i didnt even need to watch that retadred video.
