* '''Euclidean Geometry''' — The study of geometry based on Euclid's 'Elements'.
* '''Axiom (Postulate)''' — A statement accepted as true without proof.
* '''Point''' — That which has no part; a position in space.
* '''Line''' — A breadthless length.
* '''Plane''' — A flat surface that extends infinitely.
* '''Parallel Postulate''' — Euclid's 5th postulate: through a point not on a line, exactly one parallel line can be drawn.
* '''Theorem''' — A statement that has been proven based on axioms and previously proven theorems.
* '''Congruent''' — Identical in shape and size.
* '''Similarity''' — Having the same shape but not necessarily the same size.
* '''Pythagorean Theorem''' — In a right triangle, a² + b² = c².
* '''Construction''' — Creating geometric figures using only a straightedge and a compass.
* '''Q.E.D. (Quod Erat Demonstrandum)''' — "Which was to be demonstrated"; used at the end of a mathematical proof.
