Learn how to show that a line is tangent to a circle by applying the quadratic formula

The video tutorial explains how to determine if a line is tangent to a circle. It begins by defining a tangent line as one that touches the circle at exactly one point and forms a right angle with the radius. The instructor then demonstrates how to use the Pythagorean theorem to verify if a line is tangent by checking if the theorem holds true, indicating a right angle. The example provided involves calculating squares of given lengths and confirming the equality. The tutorial concludes by applying this method to solve related questions.

Explain the process of verifying if the Pythagorean theorem holds true for the given triangle.
