Today – Monday, October 22, 2012  White Board Review  Independent practice/ Check homework  QUIZ : Friday

REVIEW: Parallel, Perpendicular, and Lines

REMEMBER… PARALLEL LINES: Lines that never intersect and are coplanar. PERPENDICULAR LINES: Lines that intersect at a right angle. SKEWED LINES: Lines that are non-coplanar and do not intersect.

Using the figure below, identify the following:

REVIEW: Naming Angles

Using the diagram below, define all the following terms: If it is difficult to name each angle by its vertex, then rewrite each angle as numbers.

REVIEW: Identifying Angles

Using the diagram below, identify all of the following angles: Corresponding Angles:Alternate Interior Angles: Alternate Exterior Angles:Supplementary Angles: Consecutive Interior Angles:Vertical Angles: Adjacent Angles:Linear Pair:

Using the diagram below, define all the following terms: Corresponding Angles:Alternate Interior Angles: Alternate Exterior Angles:Supplementary Angles: Consecutive Interior Angles: Vertical Angles: Adjacent Angles: Linear Pair: *same as supplementary angles

Vertical AnglesCorresponding Angles Adjacent AnglesAlternate Interior Angles Linear AnglesAlternate Exterior Angles Consecutive Interior Angles Supplementary Angles You can rename each angle to make it easier to label.
