Question

A) what additional info is needed to prove the triangles are congruent by ASA postulate, explain.

b) what additional info is needed to prove the triangles are congruent by the HL theorem, explain.

Answer 1

See below

Explanation:

A) If
`DF\cong GH`, then both triangles will be congruent by the ASA postulate

B) If
`DE\cong GI`, in addition to one of the corresponding leg pairs being congruent to each other (so EF+IH or DF+GH), then the triangles will be congruent by the HL theorem
