Bruh no one is helping me with my questions anymore so could someone please help me on this :/ which of these statements are true

1. Vertical angles formed by intersecting lines are directly across from each other and are sometimes congruent.

2. An angle bisector divides an angle into two congruent angles

3. A midpoint divides a line into two congruent lines.

4. Perpendicular lines form congruent right angles.

5. An angle measuring 225 degrees is obtuse.

6. If two angles form a linear pair, then they are complementary.

step-by-step explanation:

b and c

all the angles opposite to the angle 150 would be 150 and all the angles that are next to 150 are 30 because they equal 180 it you add it up.

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.
