If three tangents to a circle form an equilateral triangle, prove that the tangent points form an equilateral triangle inscribed in the circle. 25. A circle is inscribed in a quadrilateral whose four angles have measures 86, 78, 99, and 97. Find the measures of the four arcs between consecutive points of tangency.
