hint: TU is 3 times as big as QR so ST will be 3 times as big as PQ

yeah that is pretty much similarity, a 'zoom' in a by a certain amount sorta
DanJS
  • DanJS
corresponding sides of the figure, will be in the same ratio, or proportion (a/b

12/3 = 8/2 = ..

  • matthew120
i can only pick one
DanJS
  • DanJS
you are moving from larger to smaller, so you want the inverse of that scale, the larger is 4 times larger than the smaller, or the smaller is 1/4 the larger
DanJS
  • DanJS
for similarity and congruence, match up the sides in ratios like that, you can solve for missing things if you need to

  • matthew120
i think its a
DanJS
  • DanJS
th esmaller figure is 1/4 the size of the original, that is the scale, notice the ratio of the sides 2/8 = 3/12
DanJS
  • DanJS
reduces to 1/4
matthew120
  • matthew120
i got a 80
DanJS
  • DanJS
all the sides on the smaller one are 1/4 the size of the larger corresponding size, that is the zoom scale factor to change from small to large lengths
DanJS
  • DanJS
look ar the properties of similar figures, you will see that sides are in proportion
