Area and volume
Area measures planar regions and volume measures spatial regions in corresponding squared or cubed units.
Coordinate geometry
Coordinates translate geometric conditions into equations and algebraic calculations.
Law of sines
In a triangle, each side divided by its opposite-angle sine has the same value.
Radians
Radian measure is arc length divided by radius.
Sets
A set is a collection of distinct objects; membership is different from inclusion.
