## DrPepperx3 Group Title help with 4 questions please? :c medal! 7 months ago 7 months ago

1. DrPepperx3 Group Title

a. a perpendicular to a given line from a point on the line b. a line segment congruent to a given line segment c. the perpendicular to a given line from a point not on the line d. the perpendicular bisector of a line segment

2. Directrix Group Title

@DrPepperx3 I don't understand what the question is. I see the four options but they are not questions. So, please post what it is that we are to figure out here, okay?

3. DrPepperx3 Group Title

I attached a picture to go along with it :)

5. Directrix Group Title

The picture looks like part of a construction of something. But, there is no question with the picture.

6. DrPepperx3 Group Title

ooohh im sorry! hold on

7. DrPepperx3 Group Title

Which construction is illustrated above?

8. Directrix Group Title

Okay. I understand now.

9. Directrix Group Title

Do you think the construction is this: a. a perpendicular to a given line from a point on the line Yes/No

10. DrPepperx3 Group Title

no

11. Directrix Group Title

I also think "no" because there is no given point where the pink ray is intersected by the dashed segment.

12. DrPepperx3 Group Title

that's what I was thinking!

13. DrPepperx3 Group Title

im taking a guess but I think its D

14. Directrix Group Title

I don't see any markings to indicate that this is correct: b. a line segment congruent to a given line segment And, three of the four answer options have "perpendicular" in them so I think it has to be c) or d) because we ruled out a).

15. DrPepperx3 Group Title

hmm so C or D

16. DrPepperx3 Group Title

im going to go with my first guess and say D what do you think?

17. Directrix Group Title

There is no segment in the diagram that has been bisected. That is a ray there in pink and a ray has infinite length.

18. Directrix Group Title

So, I don't agree with D.

19. Directrix Group Title

The construction of a perpendicular bisector of a segment looks like this: (see below) |dw:1386060914291:dw|

20. DrPepperx3 Group Title

ohhh I was thinking it was a segment that has been bisected

21. Directrix Group Title

So, that leaves which option to be correct?

22. DrPepperx3 Group Title

C !

23. Directrix Group Title

Correct. The pink angle is part of the diagram just to throw you off. c. the perpendicular to a given line from a point not on the line Here's how the construction goes: |dw:1386061121384:dw|
