What is the Definition of Congruent Triangles - Congruent Triangles
👉 Learn about congruent triangles theorems. Two or more triangles (or polygons) are said to be congruent if they have the same shape and size. There are many methods to determine whether two triangles are congruent. Some of the methods include: (1) The SSS (Side Side Side) congruency the

What is an Included Side of a Triangle - Congruent Triangles
👉 Learn about the included angles of a triangle. An included angle of a triangle is the angle between two sides of a triangle. An included side of a triangle is the side between two angles. To show that two triangles are congruent by the side angle side (SAS) congruency theorem, we must s

Angelica Babei - A family of $\phi$-congruence subgroups of the modular group
In this talk, we introduce families of subgroups of finite index in the modular group, generalizing the congruence subgroups. One source of such families is studying homomorphisms of the modular group into linear algebraic groups over finite fields. In particular, we examine a family of no

Mod By A Group: Generalized Modular Arithmetic, from Basic Modular Arithmetic Congruence to 'Normal'
This time I wanted to tackle what it means to Mod by a Group (or rather by a subgroup) and how that can give rise to generalized modular arithmetic. I start from basic modular arithmetic congruence in the integers and used that as a vehicle to build up to the idea of 'Normal' in Abstract a
