The statement that we can make that must be true about the sides of ΔDEF is: EF > DE > DF.

Triangle Sides and angles Relationship

  • The length of the three sides of a triangle is relative to the measure of the size of the angle opposite to each of he sides.
  • That is, the longest side will be directly opposite the largest angle and vice versa.

Thus, the statements about the sides of ΔDEF are missing, however, we can make the following deductions:

  • m∠D = 103° is opposite to the longest side EF.
  • m∠F = 63° (180 - 103 - 14) is opposite to the medium side DE
  • m∠E = 14° is opposite to the shortest side DF.

Therefore, the statement that we can make that must be true about the sides of ΔDEF is: EF > DE > DF.
