Chapter 5.1

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. It is parallel to the third side and its length is half the length of that side.

Front

If VW is a midsegment of triangle KIJ, what is the relationship between the lengths of segment KI and VW?

Back

The length of segment KI is twice the length of midsegment VW.

Front

What is the length of segment KI if VW is a midsegment and its length is 4?

Back

The length of segment KI is 8.

Front

In triangle DEF, if KJ is a midsegment and its length is 7, what is the length of segment DF?

Back

The length of segment DF is 14.

Front

If PM = 9 in triangle with midpoints M, N, and P, what is the length of UV?

Back

The length of UV is 18.

Front

What does it mean for segments to be congruent?

Back

Segments are congruent if they have the same length.

Front

If NM is a midsegment in triangle, which segments are congruent to NM?

Back

Segments that are congruent to NM include UM and MT.

Front

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

Back

To find the length of a midsegment, measure the lengths of the two sides it connects, and then take the average of those lengths.

Front

What is the formula for the length of a midsegment?

Back

The length of a midsegment is given by the formula: Length of midsegment = 1/2 * (Length of third side).

Front

If the lengths of two sides of a triangle are 10 and 6, what is the length of the midsegment connecting those sides?

Back

The length of the midsegment is 8.
