Three questions for geometry buffs... help...?

Question

Somehow if you could show a picture ( I dont know if you even are able to) of the following :

* 2 lines that lie in a plane but do not intersect
* 3 lines that intersect in a point but do not all lie in the same place
* 2 planes that do not interesect

Answer 1

2 lines that lie in a plane but do no intersect...... Imagine railroad the 2 rails of a railroad track... the plane is the earths surface

3 lines that intersect in a point but do not lie in the same plane... look at the corner of any room they meet... 1 line goes up and down... 1 line goes left and right... 1 line goes forward and backward...

2 planes that do not intersect.... imagine the floor and the ceiling

what do you think of that imagery

Answer 2

I can't draw a picture, but I can explain each.

1) Imagine the plane being the floor. Take two sticks, and lie them parallel to eachother.
2) Imagine the plane again being the floor. Take three sticks, and create a 6-point "star". If you want none of them to lie in the same plane, then simply put them at angles. For example, one straight up and down, the other lying flat, and the last 45 degrees in-between.
3) Imagine two planes being pieces of paper. Lay one down, and hold the other one above it also lieing flat.

Answer 3

a) draw two parallel lines
b) draw two lines on a plane that intersect, then draw a line that pierces the plane in which the two lines lay at their intersection point (looks like the "3-d Cartesian planes")
c) draw two parallel planes

Answer 4

If a line bisects a chord (line that intersects the circle in 2 places and does not pass for the scale of the midsection) and is perpendicular to the chord, that line will pass for the scale of the midsection of the circle.

Answer 5

Here you go.

Yeah. I kick ***.
