Author:David DeShetler, Tim Brzezinski
Topic:Angles

Step 1

In the applet below, a TRANSVERSAL intersects 2 PARALLEL LINES. First, look at the four different pairs of angles by checking the boxes on the right of the applet, then answer the first question.

Step 2

Use the sliders on the right to move the lines and change the angles. As you move the lines use the "Slide Me!" slider to determine how the angles are effected by these changes. After you have tried this several time answer Questions 2 thru 5. NOTE: The two lines intersected by the transversal will remain parallel at all times!
