Answer:
The correct option is AAS.
Step-by-step explanation:
Consider the diagram below.
- It is provided that The triangles △ WXZ and △ YZX share a side <em>XZ</em>.
- Angles ∠WXZ and ∠XZY are right angles.
- Angles ∠XWZ and ∠XYZ are congruent.
If two angles are congruent it implies that they are same in degrees or radians.
So, the angles ∠XWZ and ∠XYZ are equal.
So, in the diagram below, one of the triangles have two angles that are equal to the corresponding angles on the other triangle and the two triangles share a side.
Then according to the Angle-Angle-Side (AAS) statement the triangles △ WXZ and △ YZX are congruent.
Thus, the correct option is AAS.
 
        
                    
             
        
        
        
Answer:
(C)Converting to a common denominator
Step-by-step explanation:
Given some of the steps in the derivation of the quadratic formula below:

Step 4b is derived from Step 4a by converting the left-hand side to a common denominator 4a.
Therefore, that which best explains or justifies Step 4b is:
