Midsegment Theorem (line segments)

Front

What is the Midsegment Theorem?

Back

The Midsegment Theorem states that a midsegment of a triangle is parallel to one side of the triangle and its length is half the length of that side.

What is a midsegment in a triangle?

Back

A midsegment is a line segment that connects the midpoints of two sides of a triangle.

Front

How do you find the length of a midsegment?

Back

To find the length of a midsegment, measure the length of the side it is parallel to and divide by 2.

What happens to the midsegment if the triangle is scaled up or down?

Back

The midsegment will also scale up or down proportionally, maintaining its relationship to the sides.
