Visualization of Vertical Angles
Vertical angles are opposite angles formed at the intersection of two lines. They are always equal.
What are Vertical Angles?
In geometry, vertical angles are pairs of opposite angles created when two lines intersect. They are also known as vertically opposite angles or opposite angles. A key property of vertical angles is that they are always equal in measure. For example, if two lines intersect and one of the angles formed is 45°, then the angle directly opposite to it is also 45°. This tool helps you quickly find the vertical angle for any given angle.
Formula
If ∠A is an angle formed by intersecting lines, then its vertical angle ∠B is simply:
∠B = ∠A
This means the vertical angle is the same as the given angle. Use this tool to visualize and confirm this geometric property.
Example
If you have an angle of 60°, its vertical angle is also 60°. Similarly, for an angle of 120°, the vertical angle is 120°. This tool simplifies finding and understanding vertical angles.
