Bob Bundy your welcome, and

Each course has many lessons around 20-30 and the lesson is explained then on the bottom there are questions to answer.

I feel like am student and a teacher at the same. No tests only questions and a grade for each lesson. When I finish all the lessons I submit a Credit Report Form (CRF) to get a grade for the whole course.

Thanks for the answers.

]]>Thanks for telling us the answers your teacher was expecting. I seem to remember, way back, that I thought 15 E was a posible answer.

How are you expecting to be assessed for this work ? Will you have to do an exam ?

Bob

]]>15-E

17-F

I got a 9 from 10

]]>17. I choose (F)Yes, because that means you have two lines that meet at a single point.

Explanation:

I have a common point another point on ray 1 + another point on ray 2 now I have three points and rays can be used to create a line. To have a plane two lines have to intersect in a single point, and an angle intersects in a single point.So,

I have a plane.

15- I choose A-No, because rays need one endpoint

15- Explanation:

Well as mentioned in the lesson because a ray continues indefinitely in one direction, but has a definite endpoint in the other direction, but a line needs two points to define it but it goes beyond these points it doesn't have a starting or ending point it keeps going forever.

she said #15 is incorrect. If a ray exists, then it contains the two points that are needed to define and name it. How many points are needed to define and name a line?

am going to submit this as a new answer:

#15- Two points are needed to define and name a line. So the right answer is (E)

15. In figure 1 above, can ry_EH be used to create a line?

E- Yes, because any two points can be used to make a line

But for #17- B, and E were in correct answers.

]]>I think 16C too.

I'm going to have a long think about 17.

Back after that.

LATER EDIT:

From Mathswords.com: angle = Two rays sharing a common endpoint.

I have an angle

=> I have two rays sharing a common endpoint

=> I have a common point + another point on ray 1 + another point on ray 2

=> I have three points

=> I have a plane

=> Answer B is correct

Bob

]]>17- E-No because rays cannot be extended into lines

17-Explanation:

To have a plane two lines have to intersect in a single point or are parallel. Rays have an end point they cant extend to lines. lines don't have end points to start or end them they just have two points to define them.

Ok enjoy am going to rest to

]]>See you later, going to eat.

]]>three points not lying on a line

a line and a point not lying on the line

two lines which intersect in a single point or are parallel

So doesn't that make 17-F because an angle has unites two rays in a single end point so then we have two lines that meet at a single point and two lines which intersect in a single point or are parallel are defined as a plane

]]>17. If I have an angle, do I have a plane?

A Only if you have an additional point not on the angle

BYes, because any two rays can define a plane

CNo, because there aren't enough points

DYes, because angles are big

E No because rays cannot be extended into lines

F Yes, because that means you have two lines that meet at a single point

14- I choose D-Yes, because every line segment can be extended into a line

14- Explanation:

Yes ls_BC can become a line because Every line contains a line segment, and every line segment can be extended into a line.

15- I choose A-No, because rays need one endpoint

15- Explanation:

Well as mentioned in the lesson because a ray continues indefinitely in one direction, but has a definite endpoint in the other direction, but a line needs two points to define it but it goes beyond these points it doesn't have a starting or ending point it keeps going forever.

Who are you hiding your answers from ?

In case she wants to work on it a little more without seeing mine. Also, in case someone else pops in and would like to answer the questions.

On some other forums they insist you hide your answer to any post. That allows other people to post their answers. I know we do not have that many people answering questions but...
