Step 1: We know that angle cap A cap b cap c is congruent to angle cap f cap g cap h because all right angles are congruent. Step 2: We know that angle cap b cap A cap c is congruent to angle cap g cap f cap h because corresponding angles of parallel lines are congruent. Step 3: We know that line segment cap b cap c is congruent to line segment cap g cap h because it is given. Step 4: triangle cap A cap b cap c is congruent to triangle cap f cap g cap h because of the
