It can move in either direction.
It is either the "origin of coordinates" or (more often abbreviated to) the "origin".
The right angle is formed by the intersection of the triangle's "legs".
Yes. A vector is defined as having magnitude and direction (in reference to a fixed frame). Changing either of these properties redefines the vector.
The intersection of two or more solids can either be an empty set, a point (two cones "intersecting" apex-to-apex), a line (two cubes touching along one edge), a face (two cubes, face-to-face). If the solids are "filled", the overlapping intersection will be another solid. If they are hollow, it will be a closed three dimensional figure.
you cant see it because of shrubbery or parked cars
no
An intersection is where people or things can cross paths and then continue on their same path. Ie a four way intersection. A junction is also a place to cross paths, however, the person or thing must either turn back or negotiate a new direction to continue. Like coming to a tee in the road, you must either turn left, right, or turn back but you can't go forward.
Blind IntersectionsThe speed limit for a blind intersection is 15 mph. An intersection is considered "blind" if there are no stop signs at any corner and you cannot see for 100 feet in either direction during the last 100 feet before crossing. Trees, bushes, buildings, or parked cars at intersections can block your view to the side. If your view is blocked, edge forward slowly until you can see.
If the lines are identical, then the whole lines. If not they can either not meet at all or at a single point: the point of intersection.
Lies flat when brushed in either direction to allow easy movement through their tunnels.To give them a sense of direction when moving backwards.
you only have to stop at a yield sign if there is cross traffic - if it would not be safe for you to continue through the intersection. Typically only one road at the intersection will have a yield sign - the other one will either have no sign or a stop sign/light.
When you see a flashing yellow light at an intersection you should proceed with caution.
"A driver of a vehicle which is making a turn at an intersection who is facing a steady circular yellow or yellow arrow signal shall not enter the intersection or marked crosswalk unless there is sufficient space on the other side of the intersection or marked crosswalk to accommodate the vehicle driven without obstructing the through passage of vehicles from either side."
Two continuous lines down the middle of the road indicate that you should not pass on that section of road. Most often, this is because visibility is limited on that stretch of highway.
Either option is acceptable.
In general no. The intersection of two parallel half-planes A and B is either a half-plane (either A or B, when A and B have similar orientation) or the empty set (when A and B have opposite orientation). When A and B are not parallel, their intersection is a maximal open region bounded by the two lines that define A and B, respectively. In this case, the intersection always exists and it is never a half-plane.
