Triangle ABC in quadrant one with side AB of length 2 units, triangle A prime B prime C prime in quadrant four Triangle ABC has been reflected over the x-axis to create triangle A′B′C′. Which of the following statements is true?

B′C′ = 2
A′B′ = 2
BC = 2
AC =2

B because they are basically the same AB = 2, there was no change, just a relfection, so A'B' = 2 as well Hope this helped

Step-by-step explanation:

answer: the proof is mentioned below.

step-by-step explanation:

since, given:   lines bc = ef

prove:   lines ac > ef

          statements                                           reason

1. bc=ef                                           1. given

2. ac= ab+bc                                 2. because b is the point between the  

                                                            line segment ac

3.   ac > bc                                       3. because if a line segment is equal to

                                                          the sum of two line segments then it is

                                                          always greater then each of these

                                                          individual line segments

4. ac > ef                                         4. by equality property.
