4. a line that bisects another line segment at a right angle, through the intersection point
7. A flat surface made up of points that extend indefinitely in all directions
8. made up of points with no thickness or width
9. A formula used to find the midpoint between two endpoints m=(x1+x2/2, y1+y2/2)
11. Points that lie on the same line
13. an angle of 180

20. A segment, line, or plane that intersects segments at its midpoint

1. if we have a line segment AC and a point B within it, the sum of the lengths of the segments AB and BC will give the total length of AC
2. part of a line that is bounded by two distinct end points, and contains every point on the line that is between its endpoints
3. Angles that share a common side and vertex
5. Points that lie on the same plane
6. A formula used to find the distance between two point on a coordinate plane d=√(x-x1)² + (y-y1)²
10. A measure, x, is greater than 0 degrees but less than 90 degrees
12. A point where two rays start
