There is no answer, the question is bogus.
Emma's struggling with her homework - she's not the only one! If anyone can help we'd appreciate it. Here goes - although I don't know if the diagram will work ok. Tricky Triangles Use each of the digits 0 to 9. Put one in each circle. 0 1 2 3 4 5 6 7 8 9 a) The sum of the numbers at the vertices of each shaded triangle must be 13. o /x\ o - o /x\ /x\ o - o - o /x\ /x\ /x\ o - o - o - o b) Make the numbers at the corners of each shaded triangle total 14. Emma is quite happy to do the work herself, but neither she or I can work out what the difference is between the "sum of the vertices" and the "sum of the corners". I've googled, but I'm still none the wiser. Cheers
Steph did scribe: No difference at all: just someone being sloppy with their use of language to confuse you. Mind you, that is one hell of a problem to solve. -- John (jsp) SV 650 Black it is And Naked
The vertices and the corners are one and the same thing, so is there something missing? It appears that you are being asked to obtain two different results for the same problem. Cheers, Mick.
buxtonmick did scribe: That's correct: two different solutions to the same puzzle. Why is that a problem? -- John (jsp) SV 650 Black it is And Naked
I think I've got a bit further although I'm not convinced... The dictionary says: ver·tex ( P ) Pronunciation Key (vûrtks) n. pl. ver·ti·ces (-t-sz) also ver·tex·es The highest point; the apex or summit: the vertex of a mountain. Anatomy. The highest point of the skull. The top of the head. Astronomy. The highest point reached in the apparent motion of a celestial body. Mathematics. The point at which the sides of an angle intersect. The point on a triangle or pyramid opposite to and farthest away from its base. A point on a polyhedron common to three or more sides. Therefore I think they mean the top of each triangle added together should = 13. Only thing is there's 6 vertices, and I can't get less than 15 as an answer for the sum of the vertices 0 + 1 + 2 + 3 + 4 + 5 As for making the corners add up to 14, do they mean all 3 corners? or the 2 corners that aren't the vertex? I don't remember my homework being this difficult when I was 10.
Because they've only drawn one table for her to fill in, not two - implying that the 2 questions are part of one final answer. I've just put another post up with a dictionary definition saying that the vertices are the tops of the triangles, but I can't work it out that way either.
Nice, but I'm not convinced that that's what they're asking for as they've only given her 1 chart to fill in, not 2 ( This really is a bastard of a question
Steph did scribe: I would just go along wiht the original idea that they are just not being careful with thier words. -- John (jsp) SV 650 Black it is And Naked
