it's urgent!!!
please solve this fast!!!​

Answer 1

Answer:

The lengths of tangents drawn from an external point to a circle are equal. A tangent at any point of a circle is perpendicular to the radius at the point of contact. SSS congruence rule: If three sides of one triangle are equal to the three sides of another triangle, then the two triangles are congruent.
