Properties of Tangents

• The tangent line never crosses the circle, it just touches the circle.

• At the point of tangency, it is perpendicular to the radius. From the same external point, the tangent segments to a circle are equal.
• Normally ,tangent is a line that touches the curve only at point without cutting through it.
• So, exactly 2 tangents can be drawn from the point lying outside the circle.
• Each will touch the circle at either end of the diameter.

As the conclusion,there are 2 tangents parallel to tangent pq.
