Number of triangles Puzzle - chromos - 07-11-2016 12:00 PM
The program calculates the number of triangles in the geometrical figures.
Example 1:
How many triangles are in this puzzle?
a) First we mark every important point on every line (doesn't matter in which order):
b) Next we insert every line with their points as sublists into list L0 (doesn't matter in which order):
L0:= {
{1,2,3},
{1,4,5,6},
{6,10,9},
{3,7,8,9},
{5,11,12,13,14,15,7},
{6,16,17,13,18,19,3},
{2,4},
{4,11,16,20},
{20,21,14},
{14,18,23,2},
{22,19,15,8},
{8,10},
{10,21,17,12},
{12,23,22},
}
c) Now run the program. :-)
