Explanation: two triangles that are congruent share three congruent angles and three congruent sides. What they are asking for is to list these 3+3=6 relations. Once you construct/draw the triangles ABC and EFG (they should look the identical in proportions, possibly just rotated), you can list the angles <BAC congruent to <GEF, <ABC congruent to <EFG, etc. and sides AB congruent to EF, etc., which will be 6 such statements in total. Let me know if you have questions.
