Geometry Study Guide for Chapter 3
1. Study the last 2 quizzes on 3.1 to 3.4 and do the problems without looking at the
answers.
2. Know key vocabulary: Parallel lines (pg. 126), Parallel Planes (126), Transversal
(126), Corresponding, Alternate Interior, Alternate Exterior, and Consecutive
Interior angles (pg. 128), Slope Intercept form (145), Point-Slope form (145),
Slope (pg.139). See problems 1-7 on page 167.
3. There will be several questions like 8-15 on page 167.
4. Know theorems: 3.1 to 3.7 and postulate 3.1 (Corresponding Angles Postulate).
a. Know how to do problems like 16 to 22 page 168.
b. You will need to remember complementary, supplementary, vertical angle
and linear pair angle relationships from Chapter 1.
c. Practice with problems 35-40 on page 170.
5. Know the slope formula, m =
y2 - y1
, and how to find the slope when you are
x2 - x1
given 2 points.
6. Know how to determine whether 2 lines are parallel, perpendicular or neither
given 2 points for each line. See problems 23-26 page 169.
7. Be able to write an equation in either slope-intercept or point-slope if you are
given:




The slope and the y-intercept
The slope and a point
Two points
The graph of a line with two points labeled
8. Be able to write an equation of a line that passes through a point and is parallel or
perpendicular to another line, whose equation or points are given. See problems
27-28 on page 169. Remember that 2 parallel lines have the same slope. Also,
Remember that when 2 lines are perpendicular to each other their slopes are
2
negative reciprocals. For example, if the slope of one line is , then the slope of
3
2
the other is - .

9. Know how to use the distance formula to find the shortest distance between 2
given equations of lines that are parallel. See problems 35-40 page 170.
Remember that the distance between 2 parallel lines is the length of any
perpendicular segment joining the two lines.
