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.
Middle point of line segment?
divide the line segment in half to aquire the center point
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.
What is the bi sector of a segment?
The bisector of a segment is a line that cuts the segment into exact half. For example, if the vertical line bisects the horizontal line in " T ", the vertical line cuts touches the horizontal line at the midpoint of the horizontal line
