Question

Consider the two triangles.

Answer 1

Answer:

LM is 4 units and XZ is 6 units.

Step-by-step explanation:

Now, first we have to understand that what is SSS similarity theorem. This theorem states that when sides of any two triangles are in proportion, this means that these two triangles are similar.

By the data given,

we can see that,

YZ:MN = 3:1

So, there is an assumption that ΔXYZ:ΔLMN = 3:1

Now when XY = 12, we need value of LM = 12/3 =4

So, XY: LM would become 3:1

If value of LN is given as 2, we need value of XZ = (2)*(3) = 6

Note that since ΔLMN is smaller triangle by values given, so we need to multiply value of side LN with 3 to get the value of XZ in ratio 3:1

So, by the data given in option 2, we would have all lines of both triangles in ratio of 3:1,

so,

YZ:MN = 3:1

XZ:LN = 3:1

XY:LM = 3:1

Hence, by using SSS postulate for similarity of triangles we would prove that

ΔXYZ:ΔLMN = 3:1

and also

△LMN ~ △XYZ

Answer 2

Answer:

LM is 5 units and xz is 6 units

Step-by-step explanation:

LM corresponds to XY

mn to yz and nl to zx
