Given that triangle pht is a right triangle and line hy is an altitude, what is the missing justification in the proof that (ph)^2 + (ht)^2 = (pt)^2?

The correct option is D.

Step-by-step explanation:

Given information: Triangle PHT is a right triangle and Line HY is an altitude.

According to the reflexive property, a side or an angle is congruent to itself.

If A is an angle of a triangle then using reflexive property

          (Both are right angles)

                     (Reflexive property)

       (AA rule of similarity)

Other statements and reasons are present in the table.

The missing reason is reflexive property. Therefore the correct option is D.
