We would measure the length then scale the length
 Use a ruler!!
THE FORMULA
WHY?
 The formula, derived from the Pythagoras theorem states that
square a and square b, add them together, and square root them, you
get the length of c, hypotenuse.
1.1
(CONTINUED…)
In this case we have a red line. The rise is shown by the line marked y,
and the run is marked by the line x. This corresponds to the lines a
and b from the previous picture (1.1). Now, we have the red slanted
line, which corresponds to the hypotenuse c in the previous
picture(1.1).
1.2
RUN/RISE
TO FIND DISTANCE…
 First, we square the run, which is x2 − x1 ﻿
. Then we square the rise,
which is y2 − y1,﻿
. We then add these two values together. We should get this:
(x2 − x1)squared +( y2 − y1)squared
As we have seen, the two values are equal to the hypotenuse squared.
﻿
Therefore we have to square root the equation to get the final product:
IS THERE SUCH A THING AS FINDING THE
D IS TA N CE OF A L IN E? ( V ER S US, FIN D IN G
THE DISTANCE OF A LINE SEGMENT).
There is no such thing as finding the distance of a line. A &quot;line&quot; is actually
considered to be abstract. This is because the &quot;line&quot; is considered to be
infinite and continuous in both directions. It is impossible to measure an
infinite distance. However, it is possible to find the distance of a line
segment. This is because a line segment is actually the distance between two
points of the infinite line.
COMIC!!
