Answer 1

Parallel Lines

• Coplanar lines that do not intersect.

• Arrows are used to indicate the lines are parallel.

• 
  `\textbf{Symbolic Notation:} \quad \overleftrightarrow{AB} \parallel \overleftrightarrow{CD}`

Parallel Planes

• Planes that do not intersect.

• 
  `\textbf{Symbolic Notation:} \quad \mathcal{J} \parallel \mathcal{K}`

Skew Lines

• Non-coplanar lines that do not intersect.

• 
  `\textbf{Examples:} \quad \overline{PS} \; \& \; \overline{QU}`

`\overline{TW} \; \& \; \overline{RV}\\\\ \overline{PV} \; \& \; \overline{TU}`

Explanation:

Coplanar: In the same plane.

Parallel Lines

• Coplanar lines that do not intersect.

• Arrows are used to indicate the lines are parallel.

• 
  `\textbf{Symbolic Notation:} \quad \overleftrightarrow{AB} \parallel \overleftrightarrow{CD}`

The notation for a line is a double-ended arrow placed above two points contained on the line.

The symbol denotating two objects are parallel is a vertical double line.

Parallel Planes

• Planes that do not intersect.

• 
  `\textbf{Symbolic Notation:} \quad \mathcal{J} \parallel \mathcal{K}`

A plane can be named by a capital letter (often written in script), or by the letters naming three non-collinear points in the plane.

The symbol denotating two objects are parallel is a vertical double line.

Skew Lines

• Non-coplanar lines that do not intersect.

• 
  `\textbf{Examples:} \quad \overline{PS} \; \& \; \overline{QU}`

`\overline{TW} \; \& \; \overline{RV}\\\\ \overline{PV} \; \& \; \overline{TU}`

The notation for a line segment is a bar placed above the endpoints of the line segment.
