Polynomial Roots Calculator is a set of methods aimed at finding values of  x  for which  F(x)=0  
Rational Roots Test is one of the above mentioned tools. It would only find Rational Roots that is numbers  x  which can be expressed as the quotient of two integers
The Rational Root Theorem states that if a polynomial zeroes for a rational number  P/Q  then  P  is a factor of the Trailing Constant and  Q  is a factor of the Leading Coefficient

Answer:
depends on whether you meant (1/2)/4  or 1/ (2/4)
Step-by-step explanation:
1/2                 x
---------- = -------------
4                   28
Using cross products
1/2* 28 = 4x
14 = 4x
Divide by 4
14/4 = 4x/4
7/2 =x
If you meant
1                 x
---------- = -------------
2/4                   28
1 * 28 = 2/4 x
28 = 1/2 x
Multiply each side by 2
28*2 = 1/2x*2
56 =x
 
        
                    
             
        
        
        
You didn't supply a list.  The so-called rigid transformations of translation, rotation and reflection create congruent triangles.
Generally it's dilation by a factor about a point is preserves similarity but not congruency.  Any transformation which includes such scalings but is otherwise rigid also preserves similarity but not congruency.
