Conversely, if two lines are parallel, then any transversal will make. Instead, I wrote book “Landscape of 21st Century Mathematics” that collects all these theorems by topics and, for many Theorems, provides more details and context. If a transversal makes equal alternate angles on two lines then the lines are parallel.

From 2021, I stopped updating the website. The website covers Theorems in the period 2001-2020.

Second circle theorem - angle in a semicircle.

On this page, the theorems are sorted by submission date (to arxiv or journal, whichever is first), not in the order added to the website. Also, you can download the excel document with the full list of Theorems, where you can search, sort, and filter them by date, paper title, author, journal, or subject category. Technical note First circle theorem - angles at the centre and at the circumference. You can also view theorems by broad subject category: combinatorics, number theory, analysis, algebra, geometry and topology, logic and foundations, probability and statistics, mathematics of computation, and applications of mathematics. Click on any theorem to see the exact formulation, or click here for the formulations of all theorems. If two sides of a triangle are congruent, the angles opposite these sides are congruent.
