Exercise 4 Page 400

Segments RM and MS are congruent.

Segment Bisector: MA
RS=18

Practice makes perfect

We know that segments RM and MS are congruent because they have matching tick-marks. This means that M is the midpoint of RS. Therefore, the segment bisector is MA.

Since RM and MS are congruent, they are the same length.

We can add these lengths to find the total length of segment RS.

RS = 9+9

RS=18
