<h3>Answer: SSS Postulate</h3>

The tickmarks tell us which pairs of sides are the same length.

AB = BC due to the single tickmarks
AD = CD due to the double tickmarks

So far we have two pairs of congruent sides.

The third pair of congruent sides are the overlapping or shared sides BD = BD which is true by the reflexive property (anything is congruent to itself).

Overall we have three pairs of congruent sides allowing us to use SSS. Each "S" stands for "Side".
