Step 1: Make sure that the midpoints of two sides of a triangle are connected (midsegment).

          EXAMPLE: U is the midpoint of TV and W is the midpoint of VS.

              UW  mid-segment △VST.

Step 2: Find the length of the parallel side to the midsegment

                   NOTE: The midsegment is parallel to the third side and half its length.

                                Mid-segment (UW) = 2 * TS (Parallel side to UW )

                EXAMPLE: ST = 2 * 70

                                    ST = 140
