Solution:
Reflexive property of congruence:
<em>Reflexive property of congruence means the geometric figure is congruent to itself.</em>
Option A: If 
From the definition of reflexive property, it is not true.
This is transitive property of congruence triangles.
Therefore it is false.
Option B: 
From the definition of reflexive property, it is not true.
Therefore it is false.
Option C: 
From the definition of reflexive property, it is not true.
Therefore it is false.
Option D: 
Here, ΔKLM is congruent to itself.
This statement illustrates the reflexive property of congruence for triangles.
Therefore, it is true.
Hence option D is the correct answer.
Answer:
add 4
Step-by-step explanation:
x^2-4x
Take the coefficient of the x term
-4
Divide it by 2
-4/2 =-2
Square it
(-2)^2 = 4
This is what we add to each side
x^2-4x +4 = 4
