A. 
2 and 4 
B. 
3 and 4 


C. 
2 and 3 
D. 
1 and 2 


Hint 


2. 
Find an angle that forms a linear pair with 4. 





A. 
AMH 
B. 
GMH 


C. 
GMA 
D. 
HMB 


Hint 


3. 
Do AMB and HMJ form a linear pair. Explain. 





A. 
Yes; the angles have the same vertex and have opposite rays. 
B. 
Yes; two noncommon sides are opposite rays. 


C. 
No; the angles are not adjacent. 
D. 
No; the angles are not the same measure. 


Hint 


4. 
Identify the pair of angles, 1 and 2, as a linear pair, adjacent pair, or neither in as many ways as possible. 





A. 
linear and adjacent angles 
B. 
neither 


C. 

D. 
only adjacent 


Hint 


5. 
Do 1 and TCN form a linear pair? Justify your answer. 





A. 
No; the angles are not adjacent. 
B. 
No; the angles are not the same measure. 


C. 
Yes; the angles have the same vertex and share a common side. 
D. 
Yes; two noncommon sides are opposite rays.
