This video explains how to solve problems 1 - 15 in the Unit 3 Review over Parallel and Perpendicular Lines. Problems 1- 6 are over
Lesson 3.1 which covered parallel lines, skew lines, perpendicular lines, and parallel planes. Problems 7-15 are over parallel lines
and transversal angle relationships that were covered in Lesson 3.2.
Unit 3 Review: Problems 16-22
This video explains how to solve problems 16 - 22 in the Unit 3 Review over Parallel and Perpendicular Lines. All of these problems
are the harder problems in relationship to Lesson 3.2 and 3.3 where you need to use the parallel angle relationships learned in Lesson
3.2 to solve for x.
Unit 3 Review: Problems 23-33
This video explains how to solve problems 23 - 33 in the Unit 3 Review over Parallel and Perpendicular Lines. Problems 23-26 are in
relation to Lesson 3.3 when we talked about the parallel angle relationship converse theorems.
Unit 3 Review: Problems 34-40
This video explains how to solve problems 34 - 40 in the Unit 3 Review over Parallel and Perpendicular Lines. All of these problems are
from lessons 3.5 and 3.6. Problems 34 and 35 are in trying to prove if two lines are parallel or perpendicular lines. Problems 36 uses
information about a rectangle to find the slope of the remaining sides of the rectangle. Problems 37-40 are about finding the slope of a
parallel or perpendicular line given a point and a given line.
