Yes and SSS

Step-by-step explanation:

Let’s write down the ratios to figure out the first question:

RP:MN=5:3

NP:ML=10:6

RN:LN=15:9

Notice that we can simplify all of those ratios to 5:3. That means that the sides are all similar, so yes, the triangles are similar.

For the second question: They are similar by because all sides are similar in the same ratio. That means that they are similar by the SSS similarity.

Hope that helps

none of the above.

for one of the equations to be used in the process, there has to be a term in the equation since squared is .

since there is only a term in the first equation, we cannot derive a from completing the square.
