Aset of data contains one outlier. the mean = 25, the median = 20, and the mode = 18. which of these measures of center will remain about the same if you remove the one outlier? which will not, and how will it change? explain your answer. answer fast! : )

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.
