Hello, dtech Geometry students! Welcome to Geogebra. For this activity you will be discovering the relationships of angles within parallel lines. Let's begin.
1. Construct two parallel lines.
2. Construct a transversal through these lines by first marking two points, one on each line, and then drawing a line through those points.
3. Measure each of the eight angles formed by the parallel lines and the transversal. Record the measurements.
