Question

given: ∠fhg and ∠kjg are right angles; fh ≅ kj prove: △fgh ≅ △kgj 1. we know that ∠fhg ≅ ∠kjg because they are acute angles they are vertical angles all right angles are congruent

Explanation:

Right - angles are defined as angles that measure 90 degrees. Since all right - angles measure 90 degrees, any two right - angles are congruent. In this case, ∠FHG and ∠KJG are right - angles, so they are congruent.

Answer:

all right angles are congruent
