Mathematical Similarity
Any two rectangles similar
False they are not all similar because they may all have congruent angle but they are not similar for example a rectangle 2 by 4 and 4 by 8 are but 9 by 3 is not similar.
The Scale factor for 9 by 3 and 2 by 4 is 2.25 but that does not match with 1.5
9/4=2.25 3/2=1.5
The Scale factor for 4 by 8 and 2 by 4 are both 2
4/2=2 8/4 = 2
Another thing is they most have the same general shape
all rectangles are not the same general shape
Any two equilateral triangle are similar
True because they fit all the rules the corresponding angles are congruent because equilateral triangle must have a 60 degree angles
all the scale factors are the same they can change to because the equilateral triangles can change to be the same

World Population!
I think that this was hard because of all the events. So I started mine with a curve because everything was running smoothly villages were growing. Then the graph went down to 5 million people. I had to change a lot because thought went mostly up. So I had to start all over again.I noticed that it is pretty amazing how quick the graph goes up or the population.
Math Graph
I think that the one in B, the one that is on the top in the row with two in it is too colorful that I can’t read it. The one in A is kind of lonely I think that because thats the hardest one person chose it. I like that all the graphs in C are about the same. But they all have a curl. I noticed that not all the graphs look the same. They all have different heights at different times but end up on the same number because people have different ideas on the speed. I did fast Running quick on my graph.
