Geometry
As in the case
of algebra, you don’t need to know much of the actual geometry you learned in
your geometry class for the GRE. Here is a list of facts about degrees and angles that you
should know for the GRE:
1. A circle contains
360 degrees (360o).
2. A line is a 180o angle, i.e. a perfectly flat angle.
3. When two lines intersect, four angles are formed, and the sum of these angles is 3600.
4. When two lines are perpendicular to each other, their intersection forms four 90o angles.
The
symbol used on the GRE to indicate perpendicularity is
5. Ninety-degree angles are also called right angles. A right angle on the GRE is identified by
the following symbol:
