First part (draw and label)
7. We have the points L, M, N and O.
8. A line segment (two points conected with a straigth line). We can mention OM and LM (write them with a line above the letters).
9. MO, MN and ML
10. We can name a line using two points that belong to that line. We have three points in the line so we can combine them in three ways to name the line: LM, LN and MN
11. R, S, T, U, V
12. RS and RV
13. SR, SU, SV and ST (remember to write them with the correct line above. I can not write them here in the text editor).
14. (same as 10) RS, RT and ST
15. We have 3 angles: ∠RSU, ∠USV, ∠VST
16. The sides of RSU are RS and SU (the sides of an angle are the two rays that formed the angle).
