Two lines that do not intersect are either or are coplanar, and are not coplanar. Two lines in the same plane are either or in one point. If two lines intersect at a 90 degree angle, then the two lines are Two planes that do not intersect are Erample 1: Identify relationships in space. Think of each segment in the picture as part of a line. Which line(s) or plane(s) appear to fit the description? a.) Line(s) parallel to $\overleftrightarrow{ED}$ and containing point $C$. b.) Line(s) skew to $\overleftrightarrow{ED}$. c.) Line(s) perpendicular to $\overleftrightarrow{ED}$. d.) Plane(s) parallel to plane $ABH$. Parallel Postulate -P Given line $I$ and point $P$, there is exactly one line through $P$ that is Perpendicular Postulate oP Given line $I$ and point $P$, there is exnctly one line through $P$ that is to line $l$. Erample 2: Use the diagram to answer each question. a.) Name a pair of parallel lines. b.) Name a pair of perpendicular lines, c.) Is $\overrightarrow{AB}?\overrightarrow{BC}$ ? Explain.
