Answer:
5) the triangles are similar, the ratio between MN and NP is 2/3 and the ratio between LN and NO is also 2/3 (this is because 6/9 = 2/3 and 4/6 = 2/3)
angleONP and angleMNL are the same because they are vertical angles so by SAS the triangles are similar.
6) the ratio of FE to YX is 8/12 (2/3) . The ratio of EG and XZ is 6/10 = 3/5
because these ratios are different the triangles are not similar because if they were the ratios would all be the same.
