Transversals with Parallel Line Exploration 3

Step 1

In the applet below, a [b]TRANSVERSAL[/b] intersects [b]2 PARALLEL LINES[/b].[br] [br][br]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 "[b][color=#980000]Slide Me![/color][/b]" slider to determine how the angles are effected by these changes. After you have tried this several time answer Questions 2 thru 5.[br][br]NOTE: The two lines intersected by the transversal will remain parallel at all times!

Question 1

What type of angles are these?

Alternate Interior Angles Corresponding Angles Consecutive Interior Angles Alternate Exterior Angles

Question 2

Complete the following statement: I[b]f a transversal intersects two _____________ ______________, then [color=#b20ea8]_________________ _____________________ angles[/color] are _____________________.[/b]

Question 3

If the pink angle above measures 146 degrees, what would the measure of its alternate exterior angle be?

180 degrees 34 degrees Not enough information giivenn 146 degrees

Question 4

Would your answer remain the same in Question 3 if the lines were not parallel?

Yes No

Question 5

As you moved the "[b][color=#980000]Slide Me![/color][/b]" slider, what transformation took place?

refection translation and rotation rotation translation reflection and rotation dilation
