What is the measure of Angle HAI?
Corresponding Angles: Quick Investigation
In the applet below, transversal [i]n[/i] intersects the lines [i]g[/i] and [i]i[/i]. [br][br]Interact with the applet below for a few minutes. [br]Then answer the questions that follow.
1.
Use the [b]Slope[/b] tool to measure the slopes of the two lines [i]g[/i] and [i]i[/i]. What do you notice?
2.
What does your observation from (1) tell you about lines [i]g[/i] and [i]i[/i]?
3.
If you haven't done so yet, drag the white point along transversal [i]n[/i] as far as it will go. [color=#9900ff][b]What geometric transformation is taking place?[/b][/color]
4.
If a transversal (in this case, [i]n[/i]) intersects 2 lines that have the property that you wrote in response to (2) above, what can you conclude about the pair of [color=#ff7700][b]orange corresponding angles [/b][/color]that were formed?
