## Numbers in Triangle Rows of 3 are equal rows of 4 are equal

Ok I'm new here and I don't know how to find answers to puzzles.

I've got a few and my brain isn't working.

Picture a triangle with circles in it. Place the numbers 1-10 in the circles on the triangle so that the sum of Rows of 3 are equal and the sum of rows of 4 are equal

(If the picture of the triangle doesn't come out it 1 circle on top, then 2, then 3 then 4. The perimeter has 4 circles on all three sides.

 I believe there are 12 solutions to this, which are variants on 2 different patterns. You can rotate by 120 degrees and get a "new" solution effectively, or flip it along one of the 3 axes of symmetry-- giving you 6 variants on a single solution, and 12 patterns all together, since there are 2 "core" solutions. Spoiler Two of the variants on the core solutions are: 2 7 8 3 4 10 9 5 6 1 2 8 6 4 7 5 9 3 1 10 DaveE
