2) ∠SDH and ∠SDT are right angles because SD ⊥ HT.

3) as it is given in the question.

4)  is the reflexive property.

5) ΔSHD ≅ ΔSTD by RHS congruency.

Step-by-step explanation:

Given in the question:

In ΔSHD and ΔSTD

  (Given)

   (SD ⊥ HT)

(Common)

Therefore,   (By RHS rule)

Reflexive property of congruency is defined as the property in which something is equal to itself. Hence, the reflexive property of these two triangles is
