A Note on Notation
A Note on Notation
The new SAT now uses standard geometric notation to indicate lines, line segments, rays, length, and congruence. Why is this a big deal? Because it makes interpreting questions and drawing figures more difficult. It’s possible that if you don’t know the notation, you won’t know what the question is asking you to do. So here’s a list of the correct notation. Memorize it.
Finally, you need to know the term congruent, which means “exactly the same” or “equal.” The new SAT may also test to see if you know the symbol that indicates congruence. To say that angle A is congruent to angle B, you’d write: .
