Since DE is a perpendicular bisector of FG, we can determine the following facts:
-
DE bisects FG: This means that FH ≅ GH. Therefore, \( FH \equiv GH \).
-
Right Angles: Since DE is perpendicular to FG at point H, we know that \( \angle DHF \) and \( \angle DHG \) are right angles, meaning \( \angle DHF ≅ \angle DHG \).
Thus, the two statements that must be true are:
- \( \angle DHF ≅ \angle DHG \)
- \( FH ≅ GH \)
Or, using the options provided:
- \( FG \equiv DE \) (This statement does not hold as FG and DE are not being compared like this in the context).
- \( FH ≅ GH \) (This statement is true given the properties of a perpendicular bisector).
So, the correct answers are:
- ∠DHF ≅ ∠DHG
- FH ≅ GH
These correctly represent the properties of perpendicular bisectors and their geometry.
