How many sets does an angle separate a plane?
An angle separates a plane to 3 sets: 1) Points between the 2 rays 2) Points on one of the rays 3) Points outside of the 2 rays
What are lines that lie in the same plane?
They are coplanar. ANY 2 lines would be coplanar, however a third line can be outside of the plane. just like 3 points will designate a plane and a triangle
When are four points in a plane?
Any 4 points can lie in a plane, 3 points determine a plane and just take the 4th to be say the origin.
How many points are used to name a plane?
3
How many points are needed to define a plane?
3
Can three points be noncoplanar?
No, A plane can be drawn through any 3 points. If the 3 points are collinear then they make a line and a plane can contain a line. If the points are noncollinear then they can be used to form the corners of a triangle; all points of a triangle are in the same plane.
How many planes are determined by 5 noncoplanar points 3 of which are collinear?
3
How many sets does an angle separate a plane?
An angle separates a plane to 3 sets: 1) Points between the 2 rays 2) Points on one of the rays 3) Points outside of the 2 rays
How many planes are determined by 8 noncoplanar points?
A cube has 8 non-coplanar points at the vertices and has 6 faces. This is only a partial answer...3 points determine a plane so there will be many more than 6. Your answer is going to be found by the formula n!/(n-r)! where n=8 and r=3. That gives: 40320/120 = 336
Does a plane has two points?
A plane has an infinite number of points. It takes 3 points to fix a plane i.e. you need 3 points to identify one unique plane.
What 3 parts does a circle divide a plane into?
The three parts are:the interior of the circle, the points on the circle (points on its circumference) the outside of the circle.
What kind of plane has 3 points?
Every plane has 3 or more. There is a projective (or affine) plane with only 3 points.
Three points that determine a plane?
Any 3 points determine a plane.
What are lines that lie in the same plane?
They are coplanar. ANY 2 lines would be coplanar, however a third line can be outside of the plane. just like 3 points will designate a plane and a triangle
Can two points determine a plane?
No, 2 points define a line, 3 points define a plane.
When are four points in a plane?
Any 4 points can lie in a plane, 3 points determine a plane and just take the 4th to be say the origin.
Do a plane and a ray intersection form a line?
no 2 points form a line, 3 points form a plane
