Repeat with more vertical angle pairs. In addition, angles that form a linear pair are also supplementary, so their sum is always 180 degrees. We can also say that the two vertical angles share a common vertex (the common endpoint of two or more lines or rays). According to vertical angle theorem, in a pair of intersecting lines, the vertically opposite angles are equal. In the diagram above, there are four sets of linear pairs. As vertical is the opposite of horizontal, anything that makes a 90-degree angle (right angle) with the horizontal or the horizon is called vertical.

Here, if we add in the angle measures, we'll see that vertical angles are congruent. The sum of this pair of vertical angles is 120°. For example, an angle of 30 degrees has a reference angle of 30 degrees, and an angle of 150 degrees also has a reference angle of 30 degrees (180–150). If the vertical angle measurements are not congruent, it is likely due to the lines forming them not being perfectly straight. The vertical angles theorem tells us that the angle opposite of the 60° angle must also be 60°. The measure of an angle is 30 more than its complement. Find the value of x if angles are supplementary angles. Example: If the angle A is 40 degree, then find the other three angles.
