Answer:
b. ∆DEF ~ ∆HDF ~ ∆HED
Step-by-step explanation:
When you name similar triangles, the order of the letters of corresponding angles must be in matching order.
For example, in ∆DEF, ∠D is the right angle, ∠E is the larger acute angle, and ∠F is the smallest angle.
The corresponding parts in ∆HDF are ∠H, ∠D, and ∠F.
In ∆HED, they are ∠H, ∠E, and ∠D.
The similarity statement is
∆DEF ~ ∆HDF ~ ∆HED
