We can analyze the angles based on their relationships:
1. **Angle 2 and angle 5**: Angle 2 (A-E-D) and angle 5 (the right angle formed by ray E-F and line C-D) are not complementary. They are not angles that add up to 90 degrees together.
2. **Angle 4 and angle 5**: Angle 4 (B-E-F) and angle 5 (the right angle) are indeed adjacent angles because they share a vertex (E) and a side (EF) and are next to each other.
3. **Angle 2 and angle 3**: Angle 2 (A-E-D) and angle 3 (D-E-B) are formed on a straight line (line C-D). Since they form a linear pair, they are indeed supplementary angles, adding up to 180 degrees.
4. **Angle 1 and angle 4**: Angle 1 (A-E-C) and angle 4 (B-E-F) are not vertical angles; they are adjacent angles.
5. **Angle 1 and angle 5**: Angle 1 (A-E-C) and angle 5 (right angle) are not supplementary because they do not add up to 180 degrees.
Based on the analysis, the two true statements are:
C. Angle 2 and angle 3 are supplementary angles.
B. Angle 4 and angle 5 are adjacent angles.
