Consider the proof.Given: Segment AB is parallel to line DE. Prove:

Points J and K are midpoints of the sides of triangle FGH.

Points A and B are midpoints of the sides of triangle QRS.

Point A is the midpoint of side XZ and point B is the midpoint of side YZ.

Consider the paragraph proof.Given: D is the midpoint of AB, and E is the midpoint of AC.Prove:DE = BCIt is given that D is the midpoint of AB and E is the midpoint of AC. To prove that DE is half the length of BC, the distance formula, d = , can be used to determine the lengths of the two segments. The length of BC can be determined with the equation BC = , which simplifies to 2a. The length of DE can be determined with the equation DE = , which simplifies to ________. Therefore, BC is twice DE, and DE is half BC.
