math teaser, fun with triangles
Given fourteen points draw equidistant to each other in the shape of a pyramid missing the top piece (5 bottom row, 4 the row above, 3 the row above that and finally two on the row above that which is the top), determine the number of triangles that can be drawn formed with the vertices at these points.
the picture should look like Pascals Triangle without the top point . I don't know how to draw the image of the dots properly on this website. Imagine 14 dots arranged in a pyramid without a top piece. Please give a brief explanation. good luck, have fun!
