Which construction must you do to construct a triangle given the lengths of two sides and the measure of the angle between the two sides? a) construct a 90° angle. b) construct a line parallel to a given line. c) construct an angle congruent to a given one. d) construct a line perpendicular to a given line.

In the figure below, ∠dec ≅ ∠dce, ∠b ≅ ∠f, and segment df is congruent to segment bd. point c is the point of intersection between segment ag and segment bd, while point e is the point of intersection between segment ag and segment df. the figure shows a polygon comprised of three triangles, abc, dec, and gfe. prove δabc ≅ δgfe.

In the diagram, ab is tangent to c, ab = 4 inches, and ad = 2 inches. find the radius of the circle.
