Analyze the diagram below and answer the question that follows.

Option (3)

Step-by-step explanation:

To prove ΔMTD ≅ ΔLGS,

               Statements                      Reasons

1). Segment TM ≅ GL               1). Given

2). Segment MD ≅ LS             2). Given

3). Segment TD ≅ GS             3). Additional information required

4). ΔMTD ≅ ΔLGS                   4). SSS property

For SSS property corresponding sides of the given triangles must be congruent.

Therefore, additional information required is segment GS ≅ TD

Option (3). will be the answer.
