  2. I'm confused on 20 21 22 on page 24

  3. Since when has anyone started trusting me??!!

    As for the confusion... Good!! I love that... I'll get back to you later!!

    Mr. C.

  4. I only found one other name for #1 Line XY.. Line YX. But I can't find anything else!

    ReplyDelete
  5. I can't think of a more sophisticated response for #5 other than "No, because they go in different directions". Is that even correct?

    ReplyDelete
  6. For 1-2 #16,#17 can the intersection be a single point?

    ReplyDelete
  7. Nevermind about the one above.. I really don't understand how to find intersecting planes!

    ReplyDelete
  8. I don't understand #15 on 1-2.. How can QRS be a plane? It seems like TWO planes... Because S is on a different plane than Q!

  9. I don't really understand #45..

    ReplyDelete
  10. Woops! Mistake! Up there I meant #44!

    What does "distinct" mean in #45..?

    ReplyDelete
  11. How do you figure out #4?

    ReplyDelete
  12. Btw.. My new ones are in 1-3! (The one above)

    I don't know the difference of the two in #6!

    ReplyDelete
  13. I don't understand what to do for #27.. (1-3)

    ReplyDelete
  14. I'm not sure how to do #29 either.. (1-3)

    ReplyDelete
  15. I'll check in on your answers tomorrow..
    Bye Mr.C!

  16. I wasn't sure about the second segment bisector for #5 1-3. I put line l as one bisector, but I couldn't find any others. Is point Q a bisector? Do you have to split the line into two rays?

  17. Dear Fellow Rope-Stretchers,

    fyi, our fledgling website is up and running... uhhh, well maybe crawling, but the video tutors are there for 1-2 & 1-3. Give it a try!

    I need a favor this year... instead of just saying "I don't get #572" please say something more descriptive, e.g. Julia's question above is a perfect example of giving me some hints that you are working thru the problem and I can better see where you're stuck.

    To answer your question Julia: Yes, a point can be a bisector. You can't name a ray unless you have another point (or points) on line l.

    "Distinct" can also be read as "separate and distinct"... i.e. if line m contains Points A & B, line m and line AB are two ways to name the same line... they are not two DISTINCT lines, ca-peesh?

    I'll try to answer some others tomorrow, in the meantime, why don't some of you PLEASE try your hand at answering PLEASE!!

  18. 15, 16, 17, 18? I just don't understand.

    Also, for #5 on on 1-3, I only found one segment bisector.

    ReplyDelete
  19. i also am slightly confused with #27 and 29...

    I understand what they are asking, but I am not entirely sure on how to solve it?

  20. For #20, the intersection of two planes is a line (we'll go over this in class tomorrow). So line-TS is the intersection of Plane QRS and Plane TXW. Note: Any 3 points in a plane can be used to name that distinct plane. So, Plane QRS and Plane STQ are two of several ways to name one DISTINCT plane.

  21. ... and not to worry, we will have interesting examples in class tomorrow about planes and intersections and terms like coplanar, etc.

    Read and re-read the defn's and revel in your confusion (confusion IS good!).

    See you in the am!

  22. Do I have to ask all of my questions again? But in different formatting?

    :O

    ReplyDelete
  23. 1-2:
    #1- I can't find another name for the line other than Line YX... The complete line doesn't have another name like Line m.

    #5- The only difference I can find between the rays is that they go in different directions.. Is that right?

    #15- How can QRS be a plane? It seems like TWO planes... Because S is on a different plane than Q!

    #44- The wording of it confuses me!

    #45- What does "distinct" mean in this context?

    1-3:
    #4- I don't really understand the method to finding congruent segments.. Wouldn't any segment that is one unit long be congruent? Like Segment EF? Can you figure it out just like that? Or is there a more geometric way using formulas..?

    #27- Well, I figured this one out (hopefully). Can drawing a numberline/picture be used to help?
    Also, can the "coordinates" of the midpoint be just a single number?

    #29- For this one am I just overthinking it or can you just add the length of EG to 3 to find G?

    YES! Finally. :)

    ReplyDelete
  24. Ahhhh.. Never mind about #15 in 1-2! I gotsk it! That was just a dumb mistake..!

    ReplyDelete
  25. Adding onto my question of #29, I now GOTSK it.. If my theory above is correct.. I see why they are asking for coordinateSSSSSSS (Plural!) because you can add or subtract 5 from E's coordinate because the length of the segment would still be 5.. So there can be 2 possible points!

  26. Ahhh... PERSEVERANCE!! So sweet the victory!

  27. Planes are where you find them. In the 3-dimensional figure (be very careful, there are no markings to convince us that it is a rectangular prism) used for #15-26, QRS defines one plane, QRV defines another DISTINCT plane, and (for that matter) QRW defines another distinct plane. Plane-QRW is not drawn in the figure, but it would be a plane lying "diagonally" inside the box... can you see that??

    We will demonstrate in class tomorrow that ANY 3 points in space can be defined as "coplanar" respective to one another. Betch'ya just can't wait, eh?

  28. Are you going to answer any of my questions?

    ...
    Anybody?

    ReplyDelete
  29. WHAT DOES DISTINCT MEAN?!

    ReplyDelete
  30. I feel that I have addressed many of the questions with general information regarding planes and naming of planes.

    Distinct is an English language word... you can look it up! Draw three non-collinear points - A, B, & C. Line-AB is a distinct line from Line-BC. Now draw point D on Line-AB. We can now name that line as Line-AD (or Line-DA). We've named the line differently, but it is NOT a different (distinct) line from the original Line-AB.

    Ca-peesh??
