being defined by finding the
proportions of just two of the
components, a composition can
be plotted by plotting the
proportions of just two
components.
Starting with B:

2. Measure perpendicular bisector.
3. Multiply length by fraction of A.
4. Plot point this distance along
perpendicular bisector from BC join.
5. Draw line through this point
parallel to BC.
The composition lies on this line.

components must be plotted
to allow the composition
to be plotted.
A or C must be plotted
in addition to B.
The line plotted on the previous page
(representing 50%B) is included in
blue for reference.
Composition X
30% A
50% B
20% C
of X lies on each of the three lines
plotted. Therefore, the composition lies
at the intersection of the three lines.
Plotting just two of these lines and
finding the intersection would
be
sufficient to plot the composition
but it is good
practice
to plot all three to ensure
no mistakes are made.
a reference grid makes it much
easier to plot compositions.
