90 degrees
It has a 90degree angle. You should stand up and then notice that you are a perpendicular line to the floor since you are 90degrees to the floor if you stand exactly straight up.
Several examples may be found in the privacy of your own bedroom . . . -- the angle between any two adjacent walls -- the angle between the floor and any wall -- the angle between the ceiling and any wall -- the angle between the floor and any leg of the bed -- the angle between any leg of the bed and the bed-frame
Form right angles
A line that is going straight up is perpendicular to the floor. A line that is leaning over is not perpendicular to the floor.
Two lines that are perpendicular to the same [third] line can meet at the same point, be parallel to one another or be skew. If you are not sure about that, see below for examples of all three cases.The skewness between the two perpendicular lines is the angle between the projection of one of the lines on the other.In vector analysis, if the direction vectors of the two perpendicular lines are a and b, then if x is the angle between them,cos(x) = a.b/(|ab|)where a.b is the scalar or dot product of aand b and,|a| and |b| are the magnitudes (lengths) of the two vectors.x is a measure of the skewness.Example:Imagine yourself in a cuboid room facing one of the walls. The line where the floor meets the opposite wall is the reference line.First consider the line where the left wall meets the floor and where the left wall meets the wall you're facing. Both these are perpendicular to the reference line. They meet: at the bottom-left-front corner of the room.Second, consider the line where the left wall meets the floor and where the right wall meets the floor. Both these are also perpendicular to the reference line. They never meet: they are parallel.Third, consider the line where the left wall meets the floor and the diagonal on the facing wall: from the top-left-front to the bottom-right-front. Again both these are perpendicular to the reference line. They are not parallel but they never meet either: they are skew.

stand straight up against the floor. you are a perpendicular line to the floor since you make a 90degree with with the floor

lane lines are mostly perpendicular to the floor of the pool except for the slope. when swimming freestyle your arm formsan acute angle
the wall
standing on the floor Perpendicular is when a straight line is 90 degree to another line
45 degrees is the angle halfway between the floor and the wall of your house.
Yes. Take a look at the corner of your room, where two walls meet the floor.
stand up... that is a perpendicular line right there. you are 90 degrees with respect to the floor.
