Can someone check my answer please :) Place the following steps in a logical order to help prove that segment DE is half the length of segment AC Theorem: The segment joining the midpoints of two sides of a triangle is parallel to the third side and half its length.
Help please ! The first link is to the picture provided . Th first attachment is the proof in the wrong order . The second attachment are the answer choices .
Im pretty sure it was the first one can you check?
@Ashleyisakitty @ganeshie8 can you check this please ??
@Mertsj @robtobey can you please check my answer
Choose the last one. It has the given first.
@Mertsj look at this http://assets.openstudy.com/updates/attachments/52e07452e4b0b5e90a1663a2-arilove1d-1390441783601-capture243.png
the given is statement lll
Typically , in a proof, you begin with what is given and go from there.
In the question the proof is out of order so you have to put it in order
Statement Justification I Segment DE is half the length of segment AC. By substitution II Segment DE is parallel to segment AC. Slopes of parallel lines are equal. III The coordinates of point D are (4, 5) and coordinates of point E are (5, 3) Given IV Length of segment DE is Square root of 5 and length of segment AC is 2 multiplied by the square root of 5. By the distance formula
So what is your answer choice?
I believe its III The coordinates of point D are (4, 5) and coordinates of point E are (5, 3) Given I Segment DE is half the length of segment AC. By substitution IV Length of segment DE is Square root of 5 and length of segment AC is 2 multiplied by the square root of 5. By the distance formula II Segment DE is parallel to segment AC. Slopes of parallel lines are equal.
I would go with III, II, IV I
yw
III, II, IV I is not an option
