Expert Answer

If middle points of two sides of triangle is joined together by a line, then this line is parallel to the third side of triangle

and its length is half of third side.

For example, R and Q are mid points of AB and AC respectively.

Line RQ is parallel to side BC . RQ = (1/2) BC.

Above mentioned property is used to get the required line segments and they are marked in the figure.
