Geometry help please.

Set A

Step-by-step explanation:

Reflection is a flip, so you need to flip the rectangle over the x-axis. So since the rectangle will end in quadrant 4, the x coordinates are all positive and the y coordinates are all negatives. Look at your choices and see what you can eliminate. Set B & C are out because they have negative x coordinates. Set D is out because the y coordinates are NOT negative, so that leaves Set A as the answer.

300pi

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.
