Questions and Answers

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

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.
