Example Question #1 : How To Find The Endpoints Of A Line Segment
What is the length of a line with endpoints and ?
The formula for the length of a line is very similiar to the pythagorean theorem:
Plug in our given numbers to solve:
Example Question #2 : How To Find The Endpoints Of A Line Segment
The points A, B, and C reside on a line segment. B is the midpoint of AC. If line AB measures 6 units in length, what is the length of line AC?
If B is the midpoint of AC, then AC is twice as long as AB. We are told that AB=6.
The diagram shows six units between points A and B, with B as the midpoint of segment AC. Therefore segment BC is also six units long, so line AC is twelve units long.
