2. if mLWIN = 100⁰ and mLMOR=100⁰; then LWIN & LMOR are (a)  

3. Line a and line b are on the same plane and they do not intersect, therefore

line a and line b are (a)  

4. mLD = 37⁰ and mLF = 53⁰ therefore,

LD and LF are (a)  

5. L6 & L7 are adjacent angles. mL6 + mL7 = 180⁰ therefore

L6 & L7 are (a)
