Question

Gina wrote the following paragraph to prove that the segment joining the midpoints of two sides of a triangle is parallel to the third side. Given: ∆ABC Prove: The midsegment between sides Line segment AB and Line segment BC is parallel to side Line segment AC. Draw ∆ABC on the coordinate plane with point A at the origin (0, 0). Let point B have the ordered pair (x1, y1) and locate point C on the x-axis at (x2, 0). Point D is the midpoint of Line segment AB with coordinates at Ordered pair the quantity 0 plus x sub 1, divided by 2; the quantity 0 plus y sub 1, divided by 2 by the Midpoint F

Answer 1

Which statement corrects the flaw in Gina's proof?

The coordinates of D and E were found using the slope formula.

Segments DE and AC are parallel by definition of parallel lines.

The coordinates of D and E were found using the Distance between Two Points Postulate

The slope of segments DE and AC is not 0.

Answer 2

Are you also trying to finish geometry before school starts on flvs?

Answer 3

yes
