Girard's theorem | Mathematics | Euclidean & Non-Euclidean Geometry | We observe that for any triangle drawn with great-circle arcs on the surface of a sphere, the sum of its interior angles is always greater than two right angles, and this surplus seems to increase as the triangle gets larger. Given that our familiar planar formulas for area based on side lengths are inapplicable here, ... | Here in the Low Countries, our ships of the East India Company chart the entire globe, and the practical needs of our navigators and cartographers present us geometers with new and urgent puzzles. It has long been an object of curiosity, and now of great practical import, that the familiar rules of our planar geometry ... | ## Introduction
**Research question** – *For a spherical triangle whose sides are arcs of great circles, can the exact surface area be obtained directly from its three interior angles, without reference to side lengths?*
On the curved surface of the Earth (or any sphere) planar formulas fail: the interior angles ... | [

Given that our familiar planar formulas for area based on side lengths are inapplicable here, ... | Though my days are spent wrestling with the roots of equations in my work on algebra, it is a persistent curiosity, this matter of triangles drawn upon the surface of a globe. Here in the Low Countries, with our great ships sailing to the Indies, the problem is not merely academic. Navigators, astronomers, they know we... | ## Introduction
**Research question** – *Can the surface area of a triangle drawn on a sphere by great‑circle arcs be obtained directly from its three interior angles, without using side lengths?*
On a sphere the Euclidean rule “angle sum = 180°” fails; the sum exceeds 180° by an amount that grows with the triang... | [

My work on algebra and trigonometry has filled my days, yet this old puzzle from the navigators and astronomers continues to vex me.
[Motivation for the idea]
It is a known curiosity that on the surface of a globe, the three angles of a triangle drawn with great-circle arcs do not sum to two right an... | **Title:**
*Area‑Angle Relation for Spherical Triangles – A Direct Formula Using Only the Three Interior Angles*

## Introduction
**Research question** –
On a sphere, a triangle formed by three great‑circle arcs has interior angles whose sum exceeds two right angles. The surplus (the *spherical excess*) gro... | [
