Final answer:

Vertical angles and linear pairs in geometry are related to angles formed by intersecting lines. A vertical angle is opposite another vertical angle with the same vertex. A linear pair is formed by two adjacent angles that share a common side and add up to 180 degrees.

Step-by-step explanation:

In geometry, vertical angles and linear pairs are related to angles formed by intersecting lines. A vertical angle is formed by two lines that intersect, and it is opposite another vertical angle with the same vertex. A linear pair is formed by two adjacent angles that are formed by intersecting lines and share a common side.

Let's say we have two vertical angles, m and n, and two linear pairs, 1-2 and 3-4. To prove their relationship, we can use the properties of vertical angles and linear pairs.

  1. For the vertical angles m and n, we can show that they are congruent. Since they are opposite angles formed by intersecting lines, they have the same measure.
  2. For the linear pairs 1-2 and 3-4, we can show that their angles add up to 180 degrees. Since they are adjacent angles formed by intersecting lines and share a common side, their measures sum up to a straight angle.
