Step-by-step explanation:
The two triangles are similar if the ratio of the corresponding sides are proportional.
The ratio of the corresponding sides are:



The set of ratios which could be used to determine if one triangle is a dilation of the other is

If there are multiple correct options then check this one too.

 
        
             
        
        
        
∠1 is an angle formed by the two lines PF and YF at point F
We can also call this angle as ∠PFY because it indicates the point F in the middle where the angle is formed
We can call this angle as ∠YFP because it also indicates the point F in the middle where the angle is formed
we can also call this angle ∠F since F is the point where the angle is formed.
Correct answer: ∠PFY, ∠YFP, ∠F
        
             
        
        
        
Ok, a=f/m
What we need to do is isolate the variable, m.
  a=f/m
*m  *m
a*m=f
m*a=f
/a     /a
m=f/a
There's your answer.
