Answer 2

$\huge\sf\underline\blue{Answer}$

A tangent to a circle forms a right angle with the circle's radius, at the point of contact of the tangent. Also, if two tangents are drawn on a circle and they cross, the lengths of the two tangents (from the point where they touch the circle to the point where they cross) will be the same.
