1. The problem asks to identify which two statements about perpendicularity (\(\perp\)) and parallelism (\(\parallel\)) between vectors are both true.
2. Recall the definitions:
- Two vectors are perpendicular if they meet at a right angle (90 degrees).
- Two vectors are parallel if they lie along the same line or in the same direction.
3. Given the graph description, we analyze each statement:
- Statement 1: \(\vec{DI} \perp \vec{JG}\) and \(\vec{KF} \perp \vec{JG}\)
- Statement 2: \(\vec{DI} \perp \vec{KF}\) and \(\vec{DI} \perp \vec{EH}\)
- Statement 3: \(\vec{EH} \perp \vec{JG}\) and \(\vec{KF} \parallel \vec{DI}\)
- Statement 4: \(\vec{EH} \perp \vec{JG}\) and \(\vec{KF} \parallel \vec{JG}\)
4. From the graph, the two lines with points D, E, F and K, J, G, H are parallel lines intersected by transversals.
5. Since \(\vec{EH} \perp \vec{JG}\) is true (given perpendicular marks at E and H), and \(\vec{KF} \parallel \vec{DI}\) is true because both lie along the same parallel line, Statement 3 is true.
6. Also, \(\vec{EH} \perp \vec{JG}\) is true, but \(\vec{KF} \parallel \vec{JG}\) is false because \(\vec{KF}\) is not parallel to \(\vec{JG}\) (one is transversal, the other is a line), so Statement 4 is false.
7. Statement 1 is false because \(\vec{DI} \perp \vec{JG}\) is false (both are on parallel lines, not perpendicular), and \(\vec{KF} \perp \vec{JG}\) is false.
8. Statement 2 is false because \(\vec{DI} \perp \vec{KF}\) is false (both on the same line), and \(\vec{DI} \perp \vec{EH}\) is false.
9. Therefore, the two statements that are both true are those in Statement 3: \(\vec{EH} \perp \vec{JG}\) and \(\vec{KF} \parallel \vec{DI}\).
Final answer: Statement 3 is true.
