4. Points on a polygon where the sides or edges of the object meet or where two rays or line segments meet
5. A point that marks the end of a line segment, a ray, or an interval
9. Lines are _______ if they lie in the same plane and are the same distance apart over their entire length
11. Measures the total length around the outside of a shape
12. The length of the starting and stopping points of a particular line segment
13. Is a point, line, or curve common to two or more objects

1. In elementary geometry, two geometric objects are ____________ if they intersect at a right angle. A line is said to be perpendicular to another line if the two lines intersect at a right angle
3. The inverse of a value or a number
6. A pair of numbers, (x, y), that indicates the position of a point on a Cartesian plane
7. A number that describes both the direction and the steepness of the line. (rise over run)
8. part of a line that has defined endpoints.
10. The point at the exact middle of a line segment, located at the average of the x coordinates and y coordinates of the end points
