Alice Adjusts Transversals, Parallel Lines, Angles: Protractor Version
Parallel lines never intersect. For this reason, parallel lines have special properties. Let's investigate what happens when you CUT parallel lines with another line.
The line that cuts parallel lines is called a transversal. This is a vocab word to know.
In this app, a transversal intersects 2 parallel lines. Use the points and slider to move them around. Then, use the protractor to find the measure of the 8 angles shown. Record them too.
