4
What other things are we going to be doing for the rest of these 5 weeks? Why are fractions important? More on Y=mX+b
5
Results from Meeting One Multiplication facts Operating on fractions Solving equations Order of operations 1 2 3 4 5 6 7 8 Key: Needs review Better Has it covered
6
Operating on Fractions What scales would you use on the X and Y axes to represent this data? Decimals (another pre-skill)

12
Having trouble with slope? Try using the slope formula: EXAMPLE ON BOARD
13
Having trouble with y-intercept? Plug-in both the slope and the X and Y value from a point that you know, and then solve for b FIRST PROBLEM SET
14
Is made by two lines, rays, or segments that meet (at the vertex) Has size (measured in degrees) Is described using three points
15
Some exact sizes are named: Right (90 o ) Straight (180 o )
17
Some ranges of sizes are named: Acute (between 0 o and 90 o ) Obtuse (between 90 o and 180 o )
21
Some combinations are named: Adjacent (two that share a ray) Opposite (two that are across an intersection of lines)
24
More combinations are named: Complementary (add up to 90 o ) Supplementary (add up to 180 o )
25
You can eye-ball the categories You’ll also need to find angle size exactly by measuring with a protractor EXAMPLE ON BOARD
26
Measure angles on paper using a protractor Identify individual angles as right, straight, acute, or obtuse Identify pairs of angles as adjacent, opposite, complementary, or supplementary SECOND PROBLEM SET
28
Some combinations are named: Perpendicular (meet at 90 o ) Parallel (never meet, have same slope)
31
Parallel lines have same slope (m) EXAMPLE ON BOARD
32
Perpendicular lines have slopes that are each other’s opposite and reciprocal EXAMPLE ON BOARD
33
A line that crosses or bridges two parallel lines is called a transversal
34
When a transversal crosses parallel lines, there are many pairs of equal angles – use color!
35
Corresponding angles
36
Alternate interior angles
37
Alternate exterior angles
38
Identify perpendicular and parallel lines Find the slope of a line based on the slope of a line that is parallel or perpendicular to Find missing angles’ sizes where parallel lines are crossed by a transversal THIRD PROBLEM SET
