The Triangle Midsegment Theorem

Front

What is the Triangle Midsegment Theorem?

Back

The Triangle 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 segment that connects the midpoints of two sides of a triangle.

If TS is a midsegment of triangle GHI and its length is 8, what can you say about the sides GH and HI?

Back

GH and HI are each twice the length of TS.

What is the relationship between a midsegment and the sides of a triangle?

Back

A midsegment is parallel to one side of the triangle and its length is half of that side.

Front

What does it mean for segments to be parallel in the context of triangles?

Back

Parallel segments do not intersect and maintain a constant distance apart.

How do you find the length of a midsegment in a triangle?

Back

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