Operating on Fractions What scales would you
use on the X and Y axes to represent this data?
Decimals (another pre-skill)
Warm-up
1) Operating on Fractions
2) Operating on Fractions
3) What scale for these axes?
(See Board)
4) Operating on Decimals
What have we covered, so far?
Plane Point
Line
Angle
Flat (2-D) Shapes
Solids (3-D)
Having trouble with slope?Try using the slope formula:
EXAMPLE ON BOARD
Line (continued)
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
Line (continued)
Is made by two lines, rays, or segments that meet (at the vertex)
Has size (measured in degrees)Is described using three points
New Topic: Angle
Some exact sizes are named:Right (90o)
Straight (180o)
Angle (continued)
Some ranges of sizes are named:Acute (between 0o and 90o)
Obtuse (between 90o and 180o)
Angle (continued)
See any acute angles?
I count 8 acutes, at the least
How about obtuse angles?
Some combinations are named:Adjacent (two that share a ray)
Opposite (two that are across an intersection of lines)
Angle (continued)
Adjacent acute and obtuse angles
Adjacent acute angles
More combinations are named:Complementary (add up to 90o)
Supplementary (add up to 180o)
Angle (continued)
You can eye-ball the categories
You’ll also need to find angle size exactly by measuring with a protractor
EXAMPLE ON BOARD
Angle (continued)
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
Angle TASKS
Some combinations are named:Perpendicular (meet at 90o)
Parallel (never meet, have same slope)
Topic: Angles and Lines
'See any parallel line segments?
Are these lines parallel?
Parallel lines have same slope (m)
EXAMPLE ON BOARD
Angles and Lines
Perpendicular lines have slopes that are each other’s opposite and reciprocal
EXAMPLE ON BOARD
Topic: Angles and Lines
A line that crosses or bridges two parallel lines is called a transversal
Angles and Lines
When a transversal crosses parallel lines, there are many pairs of equal angles – use color!
Angles and Lines
Corresponding angles
Angles and Lines
Alternate interior angles
Angles and Lines
Alternate exterior angles
Angles and Lines
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
