In the triangle below, mF = 26°, mFHG = 71°, and mE = 83°.

Determine the missing reason to prove HG DE.

]supplementary angles are two angles that add up to . • complementary angles are two angles that add up to degrees. • adjacent angles share a and a • congruent angles have the measure. • an triangle has one angle that is greater than 90 degrees. • a triangle with angles 45°, 45°, and 90° would be a triangle
