Vertical Angle Calculator



Formula

To calculate the Vertical Angles:

\[ A = C, \quad B = D, \quad A = \left| B - 180 \right| \]

What are Vertical Angles?

Vertical angles are two opposite angles created by intersecting lines. In the diagram above, \(A\) and \(C\) are vertical angles, and \(B\) and \(D\) are vertical angles. Vertical angles are always equal to one another (\(A = C\)).

Example Calculation 1

Let's assume the following value:

Step 1: Use the formula:

\[ A = \left| 120 - 180 \right| = 60 \]

So, Angle A = 60 degrees, Angle C = 60 degrees, and Angle D = 120 degrees.

Example Calculation 2

Let's assume the following value:

Step 1: Use the formula:

\[ A = \left| 45 - 180 \right| = 135 \]

So, Angle A = 135 degrees, Angle C = 135 degrees, and Angle D = 45 degrees.
