How can we prove that the perpendicular line at the point of contact of a tangent to a circle passes through the center of the circle?

To prove that the perpendicular drawn at the point of contact of a tangent to a circle passes through the center, we can follow a step-by-step geometric proof using basic properties of a circle. Definitions: Let O be the center of the circle. Let T be the point where the tangent touches the circle. Let … Read more

What is a topological space in mathematics?

A topological space is a fundamental concept in the field of mathematics, specifically in topology. It provides a framework for discussing continuity, convergence, and the properties of space without necessarily relying on the concept of distance. To define a topological space, we start with a set, say X, and a collection of subsets of X, … Read more
