Transversals with Parallel line Exploration 1

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![br]

Question 1

What type of angles are these?

Corresponding Angles Alternate Interior Angles Consecutive Interior Angles Alternate Exterior Angles

Question 2

Complete the following statement: [b]If a transversal intersects two ________________ lines, then [color=#b20ea8]____________________[color=#000000] angles[/color][/color] are _____________________.[/b]

Question 3

If the pink angle above measures 52 degrees, what would the measure of its corresponding angle be? What would the measure of the gray angle be?

CA 52 degrees; Grey 128 CA 52 degrees; Grey 52 CA 128 degrees; Grey 128 degrees CA 128 degrees; Grey 52 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?

Translation Dilation Rotation Reflection
