400
A line, line segment, or ray that intersects two or more lines at different points is called what?
What is a transversal?
400
Angles that are on the same side of the transversal, one inside the parallel lines, one outside the parallel lines, "in the same part of the intersection"
What are Corresponding Angles?
400
A never ending set of points connected

500
A ray that divides an angle into two congruent parts
What is an angle bisector?
500
The line that is perpendicular to the segment and that passes through its midpoint
