Grade 7/8 Math Circles Congruence and Similarity - Solutions
... Thus, we can see that scaling any triangle by a factor by a factor f is basically the same thing as scaling the two right triangles that we can divide it into. By the result of part (a), we know that the areas of both of the right triangles 4ABD and 4BCD scale by a factor of f 2 . Since the sum of t ...

... no real number greater than or equal to ∞” or ”there is no real number less than or equal to −∞”. We also introduce the following operational rules: ∞ + ∞ = ∞, −∞ + (−∞) = −∞, ∞ + (−∞) = 0 and ±∞ + a = ±∞ for real a. It is obvious that R is not a group, the rule of associativity holds only for such ...
