Find the area of triangle ABC. Show your work and use appropriate units.

Give all possible names for the line shown. calculation tip: lines can be written with either point first.

Match each inequality to the number line that represents its solution

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.
