Triangle Midsegments

Front

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

What is the relationship between a triangle's midsegment and its parallel sides?

Back

The midsegment is parallel to the third side of the triangle and its length is half the length of that side.

Front

How can you determine if two segments are midsegments of a triangle?

Back

Two segments are midsegments if they connect the midpoints of two sides of the triangle and are parallel to the third side.

Front

If the lengths of sides AB and AC are 6 and 8 respectively, what is the length of the midsegment DE?

Back

The length of midsegment DE is 4 (half of side BC, which is 8).
