Angles
An angle measures rotation between rays sharing an endpoint.
Direct proof
A direct proof derives the conclusion from assumptions using justified logical steps.
Fubini and Tonelli theorems
Product integrals can be iterated under integrability or nonnegativity and measure-space hypotheses.
Geometric loci
A locus consists of all points satisfying specified geometric conditions.
Hausdorff spaces
Distinct points admit disjoint neighborhoods in a Hausdorff space.
