πŸ“Έ A small photo report from the Mathematical Festival, which took place on February 9 at the Economic Faculty of Lomonosov Moscow State University in Moscow. Our station 'Pythagorea game' was very popular. Three tables were not enough and children enthusiastically solved problems standing all around and even on the floor. Their parents and organizers were also curious and then could not stop solving our #puzzles. Thanks for the great festival!πŸ™ #math #mathgame #mathfestival #Pythagorea #Euclidea #conference #mathematics #geometry

@euclidea_app My solution for #euclidea 's #euclidea_puzzle_23 . AC = 6AB, so BC = 5AB. (3E) BD = ABΒ² / 2BC = 0.1AB, using aΒ² / 2b by similar iscoceles triangles and dropping a perpendicular by two circles BA and CB. (2E) BE = 2 (BDΒ² / 2AB) = 0.01AB, using aΒ² / b by similar iscoceles triangles. (2E) AF = 2 (AB + BE) = 2 (1.01AB) = 2.020AB, by doubling the line segment. (1E) Total: 8E

@euclidea_app #euclidea #euclidea_puzzle_23 9E solution using 9 compass moves only. 1. A circle centered at B passing through A is drawn and intersects ray AB again at D. 2. A circle centered at D passing through A is drawn and intersects ray AB again at E. 3. A circle centered at E passing through A is drawn and intersects ray AB again at F. 4. A circle centered at F passing through B is drawn and intersects ray AB again at G. 5. A circle centered at D passing through B is drawn and intersects ray AB again at H. Call this circle X. 6. A circle centered at G passing through H is drawn and intersects ray AB again at I. 7. A circle centered at I passing through D is drawn and intersects ray AB again at J. 8. A circle centered at J passing through D is drawn and intersects X at K (either intersection works). 9. A circle centered at K passing through D is drawn and intersects ray AB again at C. This is the required point as AC/AB = 2.020. Proof: This required a construction of point J a distance 52 away from A, from which a point a distance 1/50 can be constructed from D. This method of constructing length ratios using circles is fairly well-known and used about log2(n)+2 constructions to get 1/n. The extra move here was required because the second point to get 1/50th of the segment was not present.

The red line would divide in two equal parts the rectangle that misses two corners, each of 2 units of area. But since the upper part has lost 4 more units, to compensate this we need to move this line making the upper part gain 2 units and the lower part losses 2 units. This is acomplished by gaining a triangle of 2 units. #euclidea #euclidea_puzzle_22 @euclidea_app

2 dodecagons #euclidea #euclidea_puzzle_20 @euclidea_app Proof of maximality: Note that this problem is equivalent to constructing the shortest polygonal chain with k edges. We can WLOG that these chains link up in a clockwise manner. Now, the sides of the k segments are directed segments which cannot be parallel but can be antiparallel, and must be as short as possible to fit in the n x n grid. The heuristic for this is to generate the shortest k segments that satisfy this at the origin, and then translating them to form the polygonal chain. By ensuring the segments sum to 0, we ensure that the polygonal chain is closed. To check this sum is 0, we use the Minkowski metric (aka Taxicab or Manhattan metric), in which the distance between two points is defined as the sum of the absolute differences in coordinates between them. This has the interesting property of determining the perimeter of the smallest bounding box around a convex polygon. Using this, we note that the smallest bounding box for k=12 has a perimeter of 1+1+1+1+2+2+2+2+3+3+3+3=24, which fits within the 7x7 grid - which also has a perimeter of 24. Thus, for n=7, k is at least 12. We further note that the smallest bounding box for k=13 has a perimeter of 1+1+1+1+2+2+2+2+3+3+3+3+3=27, which doesn’t fit within the 7x7 grid. Thus, a thirteen sided shape or larger will not satisfy being fit in such a grid, so we’re done.

Paul Strait and Anders Kaseorg become the authors of a new record in #Euclidea! Almost at the same time, these two smart guys proposed two different versions of a universal solution in 8 E-moves for level 10.4 "Rotation 90Β°". Congratulations! πŸ₯³πŸ€—πŸ‘ β € A little #hint: First, you should construct a point symmetric to the center of rotation A relative to the rotated line BC, and draw circles (A, B) and (A, C). It takes 4 of 8 moves. Then it remains to understand which lines and points will be needed next (it is convenient to use Explore mode for that). β € #geometry #worldrecord #newrecord #solidgeometry #math #maths #mathgames #moremath #mtbos #edtech #iteachmath #mathematics #proof #mathchat #msmath #hsmath #mathisbeautiful #instamath #logic #puzzle #problem #solution #drawing #sketch #geometria #rotation
