and no you have to make them out of the sticks
What does the picture have to do with this question?
just showing how to make the triangles...
I'm still confused about the question. It states you have six sticks,, but you listed 7 lenghts
yeah you can mix them up
so are there 7 or 6 sticks?
there isnt two 9s
3 cm, 3 cm, 5 cm, 9 cm, 9 cm, 11 cm and 13 cm. would that be 6 or 7 sticks.?
Is this a multiple choice question?
well one of the basics of triangles is that the sum of the 2 shorter sides must me greater than the longest side
so you can 3, 3, 5 3 + 3 > 5
but you can't have 3, 3, 9 as 3 + 3 is not greater than 9...
just keep working that way
you find the number of triangles you can make... its between 6 and 10
