Combinations (the "Choose" Formula)A combination is arrangement of objects where order does not matter.

n is the number of objects available to be arranged

r is the number of objects that are being arranged.

The Triangle Method ...

We use the triangle method when the vectors are arranged tip-to-tail.

Scale: 1 cm = 2 km

Remember, we use measurements with a ruler and protractor to find the "answers."
