In a word processing document or on a separate piece of paper, use the guide to construct a two column proof proving dc || ab, given ab = cd and ad = cb. submit the entire proof to your instructor. given: ab = cd ad = cb prove: dc || ab statement reason 1.                   1. 2. ac = ac     2. 3.                     3. sss (side-side-side) 4. ∠1 = ∠4           4. 5.                           5.

Look at steps

Step-by-step explanation:

STATEMENT                                                     REASON

1.   AB = CD; AD = CB                               1.        Given

2. AC = AC                                                2.        Identity property

                                                                   (AC is the common side of the two triangles)

3.  Triangle ABC = Triangle ADC            3.        SSS (Side-Side-Side)

4. ∠1 = ∠4                                                  4.  Alternative interior angles are equal (Two lines are parallel and cut by transversal)

5.   DC || AB                                               5. Since alternative interior angles are (Two lines are parallel and cut by transversal)

                                                                       equal, the lines DC and AB are

                                                                        parallel by transversal property.

Step-by-step explanation:

The FitnessGram Pacer Test is a multistage aerobic capacity test that progressively gets more difficult as it continues. The 20 meter pacer test will begin in 30 seconds. Line up at the start. The running speed starts slowly, but gets faster each minute after you hear this signal. [beep] A single lap should be completed each time you hear this sound. [ding] Remember to run in a straight line, and run as long as possible. The second time you fail to complete a lap before the sound, your test is over. The test will begin on the word start. On your mark, get ready, start.
