Equichordal point

In geometry, an equichordal point is a point defined relative to a convex plane curve such that all chords passing through the point are equal in length. Two common figures with equichordal points are the circle and the limaçon. It is impossible for a curve to have more than one equichordal point. (Wikipedia).

Constructing the Circumcircle of an Equilateral Triangle

This video shows how to construct the circumcircle of an equilateral triangle. The steps are: 1. Construct an equilateral triangle (keep the compass the same length). 2. Construct the perpendicular bisector of any two sides. 3. Set the compass to the length of the circumcenter (created

What is an equiangular triangle

👉 Learn the essential definitions of triangles. A triangle is a polygon with three sides. Triangles are classified on the basis of their angles or on the basis of their side lengths. The classification of triangles on the bases of their angles are: acute, right and obtuse triangles. The cl

[#SoME1] A simple statement with a remarkable proof ( + Proof of Bolzano-Weierstrass Theorem)

In this video, I present a very important statement that, at first, seems quite obvious, but whose proof requires some neat reasoning. I start off by explaining everything required in order to understand the problem, and then restate it in a more rigorous way. Then, I present two proofs f
