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

Front

If the length of side WX is 24, what is the length of the midsegment KJ?

Back

The length of midsegment KJ is 12, since it is half of WX.

Front

How do you find the length of a midsegment?

Back

To find the length of a midsegment, take half the length of the side it is parallel to.

Front

What is the relationship between the angles formed by a midsegment and the corresponding angles of the triangle?

Back

The angles formed by a midsegment are equal to the corresponding angles of the triangle.
