What is a bisection point?
it is the point where something is "cut in half." So if we bisect a line, we cut it in half and the midpoint is the bisection point. That is just one example
Is a half line ab the same as half line ba?
No. A half line (also called a ray) is a linear object which starts at the first point, and extends to infinity through the second point. So the half-line (or ray) AB starts at point A, and shoots 'through' B and continues past B to infinity. The half-line BA is the other way around: it starts at point B, and then shoots 'through' A and continues past A to infinity. These two half-lines/rays end up extending to infinity in opposite directions, so they are not the same (not congruent).
What is the definition of line symmetry?
a line that cuts a figure in half and the halfs look exactly alike.
What type of arc measures exactly 180?
It is half the circumference of a circle that has an arc of 180 degrees
A half-line with a designated end point which extends in only one direction without stopping?
