What does the midline theorem state?
What does the midline theorem state?
- A line drawn from one vertex of a triangle to the midpoint of the opposite side will be equal to the length of the side it is drawn to
- A line drawn parallel to one side of a triangle, connecting the midpoints of the other two sides, will be half the length of the side it is parallel to (correct)
- A line drawn perpendicular to one side of a triangle, connecting the midpoints of the other two sides, will be half the length of the side it is parallel to
- A line drawn from one vertex of a triangle to the midpoint of the opposite side will be half the length of the side it is drawn to
What did Ana and Maria use to confirm the midline theorem?
What did Ana and Maria use to confirm the midline theorem?
- They measured the lengths of side BC and the midline using a ruler (correct)

Study Notes
Midline Theorem
- The midline theorem states that a line segment connecting the midpoints of two sides of a triangle is parallel to the third side and half its length.
Confirmation of the Midline Theorem
- Ana and Maria confirmed the midline theorem using geometric tools to measure and compare lengths and angles within the triangle.
Observation of the Midline
- They observed that the midline was parallel to side BC of the triangle, illustrating the relationship established by the midline theorem.
Length Relationship
- The length of the midline was determined to be half that of side BC, reinforcing the principle that the midline is equal to half the length of the side parallel to it.
Formation of the Midline
- Ana and Maria connected the midpoints of sides AB and AC to form the midline of the triangle, adhering to the definition and properties outlined by the midline theorem.
