Question

3/25 what are vertical angles? angles that add up to 180° angles that are opposite of each other when lines intersect angles that are adjacent to each other angles that add up to 90°

Explanation:

To determine the correct definition of vertical angles, we analyze each option:

• "Angles that add up to \(180^\circ\)" are supplementary angles, not vertical angles.
• "Angles that are opposite of each other when lines intersect" matches the definition of vertical angles (formed by two intersecting lines, opposite each other and equal in measure).
• "Angles that are adjacent to each other" describes adjacent angles, not vertical angles.
• "Angles that add up to \(90^\circ\)" are complementary angles, not vertical angles.

Answer:

B. Angles that are opposite of each other when lines intersect
