Right now I have a selected but I’m not sure if that’s right please help

True or false? many triangular shapes can be circumscribed about a given circle

Atriangle with all sides of equal length is a/an triangle. a. right b. scalene c. equilateral d. isosceles

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.
