PLEASE HELP!!: For Questions 6 and 7, determine whether each pair of triangles is similar. Justify your answer.

6.   Not similar

7,   Are similar

Step-by-step explanation:

In problem 6 one triangle is a SSA situation and the other triangle is SAS, we  cannot say the triangles are similar.

In problem 7, both triangles are a SAS situation, so we need to see if corresponding sides are in proportion.

Is 10/25 = 18/45?

10/25 = .4  and 18/45 = .4

Therefore, the triangles are similar

step-by-step explanation:

given that there are two triangles j'k'l' and jkl>

the former is got by dilating the second one.

when drawn on a grid, (graph paper) coordinates of vertices of first triangle is

(6,12)j, (9,6)k and (12,9)l

side jk has length = distance between j and k

=

side j'k'=distance between j' and k'

=

ie j'k'l' has sides 1/3 of that of corresponding sides of jkl.

hence scale factor of 1/3 is used to get j'k'l'from jkl

sample answer: you can determine whether each element of the domain is paired with exactly one element of the range. for example, if given a graph, you could use the vertical line test; if a vertical line intersects the graph more than once, then the relation that the graph represents is not a function.
