no because they could do in different environment and could change.
false
when one particular variable is manipulated in a given set of variables, the result should always be the same. In keeping with this assumption, scientists expect to test one another's investigations.

There is only one scientific method, however, there is some flexibility in the way in which it is used.

Squares and circles are always similar.

The answers are usually always valid. What may or may not be valid are your assumptions about the underlying model. Also, the number of times the results should be similar depends on the number of possible outcomes and the variability in the outcomes. For example, if you spin a fair spinner with 12 equal segments, then the probability of similar results is less than likely.
Yes.
Are congruent figures always similar? Yes.
Not always, sometimes two obtuse triangles are similar and sometimes they are not similar.
yes
Cuboids are not always similar.
