Chapter 3 Parallel and Perpendicular Lines

Section 3.1 Identify Pairs of Lines and Angles HW #13 pg. 150#7-10, 18-23, 34, 35, 37DefinitionsParallel LinesLines that do not intersectSkew LinesLines that do not intersect and are not coplanar Parallel Planes Planes that do not intersect PostulatesParallel PostulateIf there is a line and a point not on the line, then there is exactly one line through the point parallel to the given linePerpendicular PostulateIf there is a line and a point not on that line, then there is exactly one line through that point that is perpendicular to that line. Definitions TransversalA line that intersects two or more coplanar lines at different pointsCorresponding AnglesAngles with the same positionAlternate Interior Angles Angles between the two lines and on opposite sides of the transversalAlternate Exterior Angles Angles outside the two lines and on opposite sides of the transversalConsecutive AnglesAngles in between the two lines and on the same side as the transversal ExampleName the angle pairs
