Good morning zee-f and bobbym,
I think 16C too.
I'm going to have a long think about 17.
Back after that.
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
I posted this to my teacher:
15- I choose A-No, because rays need one endpoint
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.
17. If I have an angle, do I have a plane?
17. I choose (F)Yes, because that means you have two lines that meet at a single point.
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.
These are the correct answers
I got a 9 from 10
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 ?
Thanks for the answers.
In mathematics, you don't understand things. You just get used to them.
If it ain't broke, fix it until it is.
Your welcome Bobbym...
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.
