21 ° + 105 ° + ∠C = 180°. 126 ° + ∠C = 180 °. Subtract 126° from both sides. ∠C = 54 °. In triangles ABC and DEF, we have. ∠A = ∠F = 21 °. ∠E = ∠C = 54 °. Two angles of one triangle are congruent to two angles of another triangle. By Third Angle Theorem, the third pair of angles must also be congruent.
