Alternate Interior Angle Calculator

Understanding Alternate Interior Angles

In geometry, when two parallel lines are intersected by a transversal, alternate interior angles are pairs of angles on the inner side of each parallel line but on opposite sides of the transversal. A key property of alternate interior angles is that they are always equal.

This calculator helps you find the alternate interior angle for any given angle. Simply input the angle in degrees, and the tool will display the alternate interior angle and a visual representation. This concept is fundamental in geometry and is used in various fields like architecture and engineering for ensuring parallel structures and precise angles.

For example, if you have an angle of 60°, its alternate interior angle will also be 60°. Use this tool to quickly verify and visualize this geometric principle.
