Geometry ----- Lines and Angles Sec. 3.1 guided notes
Part A. Read Page 140 – 142 including examples in your textbook. Take out a sheet of loose leaf paper. Put
section 3.1, the title of section 3.1, objective, and the page on the paper. You will need to know/ memorize all
vocabulary, angle pairs, and symbols.
Part B. Vocabulary ---- Define the following in your own words and draw a figure for each. You will need to
know/ memorize all vocabulary, angle pairs, and symbols.
- parallel lines
- parallel planes
- skew lines
- transversal (line)
Part C. Symbols
Write the symbol for:
a) parallel
b) not parallel
Part D. Angle Pairs Formed by Transversals
1. Write the names and definitions of the angle pairs in the key concept box on P. 142. Draw one figure or
individual figures to illustrate each angle pair.
2. Next to the angle pair names and definitions, describe the placement of the angles pairs on the figure on P.
142 in your own words. In other words, describe in your own words where the angles are located or write how
to locate the angles even if the picture changes.
Practice/ Application: On a clean sheet of paper, Do P. 144 – 145 11 – 36 all.
