sarah writes a proof to show that the congruent triangles mbc and mechave corresponding sides of equal length. her proof is shown below.
there exists a series of transformations that carries mbc onto m'b'c' because they are congruent.
all transformations carry line segments onto line segments of the same length
therefore, the corresponding sides of the two triangles are the same length,
sarah's teacher says she needs to be specific about what kind of transformations she means. which of the following should sarah use instead of the word "transformations" in her proof?
o
a.
dilations, reflections, and rotations
o
b.
reflections, dilations, and translations
o
c
rotations, translations, and dilations
o
d. translations, reflections, and rotations

The table shows the relationship between the number of cups of cereal and the number of cups of raisins in a cereal bar recipe: number of cups of cereal number of cups of raisins 8 2 12 3 16 4 molly plotted an equivalent ratio as shown on the grid below: a graph is shown. the title of the graph is cereal bars. the horizontal axis label is cereal in cups. the x-axis values are 0, 20, 40, 60, 80,100. the vertical axis label is raisins in cups. the y-axis values are 0, 10, 20, 30, 40, 50. a point is plotted on the ordered pair 40,20. which of these explains why the point molly plotted is incorrect? (a) if the number of cups of cereal is 40, then the number of cups of raisins will be10. (b)if the number of cups of raisins is 40, then the number of cups of cereal will be10. (c) if the number of cups of cereal is 40, then the number of cups of raisins will be 80. (d) if the number of cups of raisins is 40, then the number of cups of cereal will be 80.
