In triangle ABC, if D is the midpoint of side AB, what can we say about the segments AD and DB?

AD = DBAD > DBAD < DBAD + DB = BC

If two triangles are similar, what is true about their corresponding sides?

The corresponding sides are equal in length.The corresponding sides are proportional.The corresponding sides are perpendicular.The corresponding sides have no relation.

In triangle DEF, if the lengths of DE, EF, and DF are in the ratio of 2:3:4, what is the ratio of the perimeter of triangle DEF to the longest side DF?

2:43:41:15:4
