Draw representations of points, line segments, rays, angles, and lines, using a ruler or straightedge.
Use symbolic notation to describe parallel lines and perpendicular lines. (b)
An angle is formed by two rays that share a common endpoint called the vertex. Angles are found wherever lines or line segments intersect.
Understand that line segments and angles are fundamental components of plane polygons.
Identify parallel, perpendicular, and intersecting line segments in plane and solid figures. (b)
Identify examples of points, lines, line segments, rays, and angles.
Describe endpoints and vertices as they relate to lines, line segments, rays, and angles.
Perpendicular lines intersect at right angles. The symbol ⊥ is used to indicate that two lines are perpendicular.
The edge is the line segment where two faces of a solid figure intersect.
A line segment is part of a line. It has two endpoints and includes all the points between and including those endpoints.
