Final answer:
Angles 3 and 6, as formed by the intersection of three lines in the given description, are vertical angles. Vertical angles are opposite each other and have equal measures.
Step-by-step explanation:
The question is about identifying the relationship between angles 3 and 6 formed by the intersection of three lines. To answer this, we need to understand different types of angle relationships.
- Adjacent angles are two angles that share a common side and vertex and don't overlap.
- Complementary angles are two angles whose measures add up to 90 degrees.
- Supplementary angles are two angles whose measures add up to 180 degrees.
- Vertical angles are non-adjacent angles formed by two intersecting lines, and they are opposite each other.
In this case, the intersection of three lines creates six angles. Angles 3 and 6, as described in the layout, are vertical angles, which means they are non-adjacent, and they are opposite each other when two lines intersect. Vertical angles are equal in measure. Therefore, the true statement about angles 3 and 6 is that they are vertical angles.
