This activity helps students review the angles formed by two lines intersected by a transversal.  In the first part of the activity, students are given a diagram of two parallel lines and a transversal and eight sticky notes numbered one through eight.  Students pair up and are engaged in a mathematical puzzle where they must determine where to place the numbered angles based on a set of given information.  The second part of the activity is made more challenging by altering the three given lines to form a triagle.  Students now have twelve angles to place given a similar set of information about pairs of angles.
