In a word processing document or on a separate piece of paper, use the guide to construct a two column proof proving that triangle adc is congruent to triangle cba given that ∠d and ∠b are right angles and dc is parallel to ab. submit the entire proof to your instructor.

given:

∠d and ∠b are right angles

dc || ab

prove:

△adc ≅ △cba

statement:

1. ∠d and ∠b are right angles

2.

3.

4.

reason:

1. given

2. if lines are parallel, then alternate interior angles are equal

3.

5. hypotenuse angle theorem
