Exploring Angle Relationships and Angles in Triangles
Use the applet below to answer the questions that appear beneath it.
Move the slider and examine the angle measures of the [b][color=#00ff00]green angle[/color][/b]. What do you notice?
Click the other checkbox to show the [b][color=#ff0000]other pair of vertical angles[/color][/b]. [br]Move the slider and examine the angle measures of the [b][color=#ff0000]two red vertical angles [/color][/b]now. [br]What do you notice?
Now that you have all four angle measures displayed, drag the slider around. What can you conclude about the relationship between vertical angles?
[size=200][size=100]Use the applet below to answer the questions that appear beneath it. [/size][/size]
1
Use the slider to adjust the measures of the [b][color=#ff00ff]pink[/color][/b] and [b][color=#0000ff]blue[/color][/b] angles. What do you notice about the [color=#ff00ff][b]pink[/b][/color] [b][color=#ff00ff]angle[/color][/b] as the [color=#0000ff][b]blue angle[/b][/color] increases?
2
In the applet above, the [b][color=#0000ff]blue angle[/color][/b] and the [b][color=#ff00ff]pink angle[/color][/b] are said to be [b]supplementary angles[/b]. Given this information, determine the supplement of a 55° angle.
3
What is the supplement of a 1-degree angle?
4
Do supplementary angles have to be adjacent? Explain your thinking.
Use the applet below to answer the questions that appear beneath it.
1.
In your own words, describe what it means for 2 angles to be complementary angles.
2.
[color=#000000]In the applet above, the [/color][b][color=#0000ff]blue angle[/color][/b][color=#000000] is said to be a [/color][i][color=#000000][b]complement [/b][/color][/i][color=#000000]of the [/color][color=#ff00ff][b]pink angle[/b][/color][color=#000000], and vice versa.[br][/color][color=#000000]Given this information, determine the [/color][i][color=#000000]complement[/color] [/i][color=#000000]of a 40 degree angle.

3.
What is the complement of a 1-degree angle?
4.
What angle measure has a complement whose measure is equal to itself?
