Introduction to Tangents of a Circle

The video tutorial explores the concept of tangents to a circle, starting with their definition and origin. It discusses the properties of tangents, including their perpendicularity to the radius at the point of contact and the infinite number of tangents a circle can have. The tutorial provides geometric proofs to demonstrate these properties and explains the concept of parallel tangents. It also covers tangents drawn from an external point, proving their congruency using triangle congruence. The session concludes with a summary of the key properties of tangents.

Describe the properties of tangents in relation to a diameter of a circle.

What happens when you try to draw a tangent from a point inside the circle?

How can we prove that two tangents drawn from an external point are equal?
