A line which has one end, but stretches off to infinity is called a ray. If we want to show an interval such as [2,infinity) which means all the numbers between two an infinity including two, we put a close dot at two and draw a ray going to the right. Similarly for (negative infinity, 2] we draw the closed dot at 2 but this time the ray goes to the left. Now if we draw an open circle, or a the out line of a dot this mean the interval (2,infinity) where we are considering all the numbers very close to two but not two itself This is an open half line and it represents an open interval.

What is a bisecting line?
To bisect is to cut or divide into halves. A bisecting line would then be a line that divides another line in half or a line that divides an angle in half.
What is the difference between a ray and a half line?
A ray begins at an endpoint and extends in only one direction.A half line does not include the endpoint.

A first step in the construction of a perpendicular bisector is to draw a n?
Open the compass to a little more than half the distance between the two points. Draw arcs from above the line to below the line from each end. This will look a little bit like an American football. The line that goes through the pointed ends of the football is the perpendicular bisector.
How does a line symmetry look?
a symetry looks like half of an object that is equal.like for example a butterfly, you draw a line in between it and, if the sides are equal it is a line of semetry.

What divides angles and line segments in half?
An angle is divided in half by the angle bisector. A line segment is divided in half by a midpoint.
Is half open plane connected?
A half-open plane, typically represented as (\mathbb{R}^2) with one side excluded (like ( \mathbb{R}^2 \setminus {(x, y) : y < 0} )), is connected. This is because any two points in the half-open plane can be joined by a continuous path that does not cross the excluded region. However, if the plane is divided into distinct regions, such as removing a line or a point, it may become disconnected. Overall, the specific structure of the excluded area determines the connectedness of the half-open plane.

When the handle is in line with the pipe, the valve is open.
