|
Looking back at the picture given with problems 8-11 on the first quiz, Name the relationship between angles 3 and 6 and explain how you would solve a problem involving those two angles:
|
Alternate interior angles. They are congruent, so you would make them equal to each other and solve. |
|
Looking back at the picture given with problems 8-11 on the first quiz, Name the relationship between angles 2 and 7 and explain how you would solve a problem involving those two angles: |
Alternate exterior angles. They are congruent, so you would make them equal to each other and solve. |
|
Looking back at the picture given with problems 8-11 on the first quiz, Name the relationship between angles 4 and 6 and explain how you would solve a problem involving those two angles: |
Same side interior angles. They are supplementary, so you would make their sum equal 180 and solve. |
|
Looking back at the picture given with problems 8-11 on the first quiz, Name the relationship between angles 1 and 5 and explain how you would solve a problem involving those two angles: |
Corresponding angles. They are congruent, so you would make them equal to each other and solve. |
|
Looking back at the picture given with problems 8-11 on the first quiz, Name the relationship between angles 2 and 3 and explain how you would solve a problem involving those two angles: |
Vertical angles. They are congruent, so you would make them equal to each other and solve. |
|
Looking back at the picture given with problems 8-11 on the first quiz, Name the relationship between angles 6 and 8 and explain how you would solve a problem involving those two angles: |
They are a linear pair. They are supplementary. Make their sum equal 180 and solve. |
