Answer:
B, C, D
Explanation:
A. Angle MLN is not equal to 120. It is equal to 60. Therefore, it is not true
B. Angle QLP is equal to 50, therefore it is true.
C. Angle NLO + angle OLP is equal to angle NLP, therefore it is true.
D. Angle QLP + Angle PLO is equal to 90. Angle MLN + angle NLO is also equal to 90. Therefore it is true.
E. Angle NLO and Angle PLO are not equal, therefore it is not true.
