Chapter 3: Parallel and Perpendicular Lines

EQ: Can you remember all we’ve covered in this chapter?

Prep work: p236(3-6, 11-14, 19-24, 29-36, 43-44)
Look at examples starting on page 232.  This is just review of middle school topics on classifying triangles by their sides (scalene, isosceles or equilateral) and angles (acute, right, obtuse or equiangular) .  These problems also use the fact that the interior angles of a triangle add to 180 degrees.

Chapter 3: Parallel and Perpendicular Lines
3.4: Proofs with Perpendicular Lines

EQ: How do you find the distance between a point and a line?

Example #5 on p.159 is similar to Cornell notes from class.

Prep work:  p160(21-23, 36)

Retake for Ch. 2 Test: p116(1-24, 26)
(On 1-4, skip inverse and contrapositive)

Chapter 3: Parallel and Perpendicular Lines
3.4: Proofs with Perpendicular Lines

EQ: How do you write equations of parallel and perpendicular lines?

Parallel lines have the same slope and perpendicular lines have slopes that are opposite reciprocals (see theorems on p157).
Examples #2, 3 and 4 will help on the prep work.

Prep work:  p160(7-15, 17-19, 25-28)

Retake for Ch. 2 Test: p116(1-24, 26)
(On 1-4, skip inverse and contrapositive)

Chapter 3: Parallel and Perpendicular Lines
3.4: Proofs with Perpendicular Lines

EQ: How do you bisect a segment with a compass?

Constructions (p.149) were covered in class along with three new perpendicular related theorems (p.150)(that aren’t too essential in my opinion since we can easily work around them with previous theorems).

Prep work:  p152(3-12, 17-20, 23, 27, 28) and Worksheet 3.4

Retake for Ch. 2 Test: p116(1-24, 26)
(On 1-4, skip inverse and contrapositive)
