Set Theory

Every field in the present world involves a set. The theory of sets was developed by German mathematician Georg Cantor while working on the “problems of trigonometric series”.

Question

### Geometry Proof Based on Circle and Inscribed Triangles

**Problem Statement:**
Given that $ AB \cong CD $, and $\triangle BCA$ and $\triangle CBD$ are inscribed, prove the following:
- $\triangle BCA \sim \triangle CBD$
- $\angle ABC \cong \angle DCB$

**Diagram Description:**
The diagram consists of a circle with four points $A$, $B$, $C$, and $D$ on its circumference. The points are connected by chords such that:
- $AB$ and $CD$ intersect each other inside the circle.
- Points $A$ and $C$ are endpoints of one chord.
- Points $B$ and $D$ are endpoints of another chord.
The triangles $\triangle BCA$ and $\triangle CBD$ are formed by these intersections.

**Directions:**
1. Identify the given congruent segments $ AB \cong CD $.
2. Demonstrate the similarity of the triangles $\triangle BCA$ and $\triangle CBD$ by comparing their corresponding angles.
3. Show that $\angle ABC \cong \angle DCB$.

This exercise involves understanding and demonstrating the properties of inscribed triangles within a circle, as well as proving the relationships between the angles and sides of these triangles based on the given conditions.
