Hi Bob Bundy,

#2- In lesson 1 in the beginning it said we are going to learn about these elements: Point, line, line segment, ray, angle, plane.

A line segment lies between two selected points therefore it makes a line because a line needs two points two define it. It makes a ray because a ray has two points with a single ended arrow over it. A line segment  has  points and it lies on points so then I have points. Counting the point that is not in the line segment with the two points from the line segment makes an angle, and plane because an angle is a union of two rays having the same endpoint and the point from the point that is not on the line segment to one point on the line segment makes a ray and to the second point from the line segment makes another point so both of the rays have the same end point which is the point that is not on the line segment. It makes a plane because a plain  needs a line and a point not lying on the line to be defined and we have that we have two points from the line segment that made a line and a point that is not on the line. I used deductive reasoning.

It is deductive  because I  recognize that I know some things about Line segments in general, and I then apply that knowledge back to the particular line segment.

I can take up to 8 courses a year am currently taking biology and geometry I finished English, PE, American government  and algebra.

Hey I submitted My answers and they were correct


1. Will every ray contain a line segment? Why? What kind of reasoning is this?

1. Yes every ray will contain a line segment because a ray has two points it starts with an end point then it goes beyond the other point, and a line only needs two points to define it and it lies between them therefore every ray has two points to contain a line segment. The reasoning is deductive I am using general information and I am using that information to predict something about something more concrete.


2. If I have two lines, will they cross? Explain fully. What postulate helps me answer this question?

2- They can and can't cross. It depends on the kind of line I am talking about if the lines were intersecting lines they will cross because intersecting lines are lines that meet at a same point so they will cross. If I have parallel lines they will never cross because parallel lines never intersect because they always have the same distance apart they will never meet no matter how much you stretched them. Parallel postulate talks about parallel lines never crossing so it can help answer this question.
