Hyperlinks and Definitions

Using hyperlinks can seamlessly connect students to additional information that we created or that someone else has posted to the interwebs. We also want to show some pages that use the tools we’ve been discussing.

Great Example Page

An early page from my Linear Algebra Notes showing LaTeX mathematics, sidebar content along with tips, hints and warnings.

Example of Using Cards

Tables can be difficult to format in MyST when displaying complicated information. However, learning to use cards provides a solid workaround for many situations. The need for a Euclidean parallel postulate is demonstrated on one of my College Geomtery course pages. The first column called Neutral Geometry shows what can proven without a parallelism axiom. The second column called Euclidean Geometry shows what additional theorems can proven with a parallelism axiom.

Definitions and the prf Environment

MyST has a prf environment the documentation for which is linked here. The prf environment provides display options for:

• Axioms

• Theorems

• Lemmas

• Definitions

Happily, the prf package numbers the items in each list for easy reference later in the document. Also, several theorems can be presented in one page without confusion.

Definition 1

An isosceles triangle is a triangle with 2 congruent sides.

Let’s have an example of a theorem, too.

Theorem 1 (Pythagorean Theorem)

Given a triangle with legs \(a\) and \(b\) and longest side \(c\) (called the hypotenuse), the triangle is a right triangle if and only if

\[a^2 + b^2 = c^2\]
