A conjecture and the paragraph proof used to prove the conjecture are shown.

Given: E is the midpoint of segment D F. Prove: 2 D E equals D F. A segment DF is horizontal with endpoints D and F. E is the midpoint of the segment.



Drag an expression or statement to each box to complete the proof.

Answer with explanation:

Given: E is the mid point of DF.

Prove: 2 DE=D F

Proof with explanation:

It is given that
\Bar{DE} is mid point of
\Bar{DF}.

1.→

So,
\Bar{DE}\cong\Bar{DF}

-------------------------By Definition of mid point

2.→ DE=E F----------------Segment Congruence Postulate

3.→DE+E F=D F ----------------Segment Addition Postulate

4.→DE+DE=D F-------------By Substitution

5.→Simplifying gives

2 DE=D F
