You did not give me the choices but think I can still answer the question.
I the answer may be:
parallelogram,
square,
or rectangle.
Answer:
Step-by-step explanation:
Given: The triangle with coordinate A(4,6), B(2,-2) and C(-2,-4). D is the mid point of AB and E is the mid point of AC.
To prove: DE is parallel to BC.
Construction: Join DE.
Proof: If we prove the basic proportionality theorem that is
, then it proves that DE is parallel to BC.
Now, Mid Point D has coordinates=
and Mid Point E has coordinates=
Now, AD= 
DB=
AE=
EC=
Now, 
=
Hence, 
Thus, By basic proportionality theorem, DE is parallel to BC.
2.5 if youre rewriting in decimal form
The answer would be d. Because the identity property of addition is that if you add zero to any number the number stays the same
