Question

1. what are two non - adjacent angles formed by two intersecting lines called?

vertical angles
adjacent angles
complementary angles
supplementary angles

Explanation:

• Vertical angles: When two lines intersect, vertical angles are non - adjacent angles. They are opposite each other and are equal in measure.
• Adjacent angles: Adjacent angles share a common side and a common vertex. They are not non - adjacent.
• Complementary angles: Complementary angles are two angles whose sum is \(90^{\circ}\). This has nothing to do with the intersection of two lines and non - adjacent angles.
• Supplementary angles: Supplementary angles are two angles whose sum is \(180^{\circ}\). This also has no relation to non - adjacent angles formed by two intersecting lines.

Answer:

Vertical angles
