Chapter 6 Section 1b
More Angle Measures
Objective: To write and solve equations to find unknown angle measures
Parallel: two or more lines in the same plane that never intersect
Perpendicular: two lines that meet at a 90 o angle
Examples:
Skew Lines: lines that do not lie in the same plane
Example:
Transversal: a line that cuts through two or more lines
Alternate Interior Angles:
The pairs of angles on opposite sides of
rsal but inside the two
the transversal but inside the two lines
Alternate Exterior Angles:
The pairs of angles on opposite sides of
the transversal but outside the two lines
Corresponding Angles:
In this figure, AB CD. The angles in matching corners
