Lines and Planes
• Point - indicates a location in space.
• Line - A series of points that extend forever in both directions.
• Ray - A part of line that goes forever in one direction.
• Segment - A part of a line that is between 2 endpoints.
Plane
• A flat surface that extends indefinitely in all directions and has no thickness.
• A piece of paper is like a plane that you write on.
• What are some other planes in the classroom?
Types of Lines
• Intersecting Lines - Have exactly one point in common because they meet one time.
• Parallel Lines - Are in the same plane and never intersect.
• Skew Lines - Lie in different planes, and never intersect and are not parallel.
Practice Naming Line Segments
• Name a pair of intersecting segments.
• Name a pair of parallel segments.
• Name a pair of skew segments.
Angles
• An angle is formed by 2 rays with a common endpoint.
• Vertex - is the point of intersection of the 2 rays.
• Name with Angle Sign, followed by 3 capital letters with the vertex in the middle.
Types of Angles
• Acute: Between 0 and 90 degrees.
• Right: 90 degrees
• Obtuse: between 90 and 180 degrees
• Straight: 180 degrees
Pairs of Angles
• Complementary: Pairs of angles whose sum is 90 degrees
• Supplementary: Pairs of angles whose sum is 180 degrees
• Adjacent: Share a vertex and a side
• Vertical: Formed by 2 intersecting lines and are opposite each other (in the X)
• Congruent: Have equal measures
