In geometry, the segment addition postulate states that if B is between A and C, then AB + BC = AC. The converse is also the same. If AB + BC = AC, then B is between A and C. The segment addition postulate is used often in proofs involving the congruence of segments.
Famous quotes containing the word addition:
“As easy mayst thou fall
A drop of water in the breaking gulf,
And take unmingled thence that drop again,
Without addition or diminishing,
As take from me thyself and not me too.”
—William Shakespeare (1564–1616)
