If two planes intersect than they intersect at exactaly one point?

Yes. If two planes are not coincident (the same plane) and are not parallel,
then they intersect in one straight line.

Can 2 rays intersect in more than 1 point?
Yes.
Why do some systems of equations have one solution?
If it is a linear system, then it could have either 1 solution, no solutions, or infinite solutions. To understand this, think of two lines (consider a plane which is just 2 dimensional - this represents 2 variables and 2 equations, but the idea can be extended to more dimensions).If the 2 lines intersect at a point, then that point represents a solution. If the lines are parallel, then they never intersect, and there is no solution. If the equations are such that they are just different ways of describing the same line, then they intersect at every point, so there are infinite solutions. If you have more than 2 lines then maybe some of them will intersect, but this is not a solution for the whole system. If all lines intersect at a single point, then that is the single solution for the whole system.If you have equations that describe something other than a straight line, then it's possible that they may intersect in more than one point.
Does a sphere have lateral area?
It is incorrect to say that sphere has lateral area. First sphere do not have sides like other geometric figure. In fact a line or plane can intersect the surface of a sphere in just one point. Sphere has no lateral side. It is enough to say surface area of sphere than lateral surface area of the sphere.
Which 3D shape has 3 faces 2 edges no vertices?
A frustrum of a cone, A sphere intersected by two planes, An ellisoid intersected by two planes, A torus (doughnut) with a radial slice removed, A torus intersected by a plane nearer than its inner radius, A cylinder, and many more.
What is the maximum number of distinct intersections of 30 different coplanar circles?
No two circles can intersect more than twice. Each circle can intersect with each other circle. Thus there ought to be 2 × 30 × (30 - 1) intersections. However, this counts each intersection twice: once for each circle. Thus the answer is half this, giving: maximum_number_of_intersections = ½ × 2 × 30 × (30 - 1) = 30 × 29 = 870.
I have to prove if two lines intersect then they intersect in no more than one point I have to assume that lines intersect in MORE than one point i have to prove tht they intersect MORE than 1 wrong?
wrong!
What are two rays that intersect at more than one point?
no they can't
Can 2 rays intersect in more than 1 point?
Yes.
Two lines intersect in more than one point?
In Euclidean plane geometry two infinitely long straight lines intersect at only one point
Can two distinct lines intersect in more than one point?
FALSE!!
Does the graph of a system of equations intersect at more than 1 point?
Sometimes. Not always.
Two lines intersect at more than one point?
Curves yes, straight lines no
How do you draw two rays that are not parallel to each other and never intersects?
that is impossible. if they aren't parrallel, and they're rays they have to intersect at some point. This is because rays spread at both ends. The above answer is only correct if the rays on drawn on the same plane or if they are drawn on convergent (intersecting) planes, so the correct answer is the two rays must be drawn on separate planes that are not convergent, since all non-parallel lines on the same plane, or on convergent planes, will eventually intersect. If they are drawn in 3 dimensions than you can avoid them intersecting. Perhaps the questions is not specific enough?
Can three rays intersect at more than one point?
No. Ray= A finite beginning and no finite end. A ray is a linear projection in one direction. If three rays begin at the same point of origin they will never intersect again given their respective directions. Same goes for the situation of them beginning at different P.O.O's; it's only physically possible for them to intersect at one point then after. (Unless of course you bring into the picture mirrors and different mediums wherein the index could possibly cause them to reflect/refract and change their paths.. then they could possibly intersect at more than one point... BUT generally/simply speaking NO three rays cannot intersect at more than one point :-) )
Can a point lie in more than one plane?
A single point lies in an infinite number of planes.
Can two rays intersect in more than one point?
no the definition is two lines intersecting once
Does a trapezoid have more than two vertices?
it has 4 vertices, a vertice is a point were two lines intersect
