This is a working model that shows how parallel lines and a transversal form different types of angles. When I turn on the switch, the LEDs highlight matching angle pairs.
For example, corresponding angles lie on the same side of the transversal and in matching corners. Alternate interior angles lie inside the lines and on opposite sides of the transversal.
To demonstrate the concept of parallel lines, a transversal, and the types of angles formed (like alternate interior, corresponding, and co-interior angles) using LEDs and a matchboard for a visually appealing and functional project.
