Explain if triangle ZHY is similar to triangle JHI. Justify your answer given the following information: HY = 3, YZ = 6, HZ = 7 and YI = 3, IJ = 12, HJ = 14
@perl

If two triangles have three pairs of sides in the same ratio, then the triangles are similar.
do we have to solve anything or is that it?
so you need to show which sides are in ratio
Using the given lengths
my draw button does not work, but see if you can label the lengths

@perl
@perl u there?
yes
3/3 = 7/14
3 / (3 + 3) = 7/14 , so that checks
HL = 3 + 3
oh ok give me a sec
wait am i supposed to solve that?
so there are three ratios, where I am comparing side of smaller triangle to side of larger triangle. HY / HI HZ / HJ YZ / IJ if all three of these ratios are equal , the two triangles are similar
HY / HI = 3 / (3 + 3 ) = 1/2 HZ / HJ = 7 / 14 = 1/2 YZ / IJ = 6/12 = 1/2 By SSS similarity postulate, the two triangles are similar http://www.mathsisfun.com/geometry/triangles-similar-finding.html
oh wow thank you so much!
