If the lengths of two of the sides of a triangle are 1 and 20,
then the third side can be
any
length between 19 and 21.
It's not possible to calculate it exactly until we know
more information about the triangle.
For example, if the triangle is a
right
triangle,
then the length of the third side is
either √401 = roughly 20.025
or √399 = roughly 19.975 .

The pyhtagorean states that to find c, use the eqaution,
.
Substitute 1 for a and 20 for b;
c^2=1+400
c^2=401
c=
which is about 20.02
Hope this helps.
