Points, Lines, Rays, and Angles

 

We have covered the definitions of points, line segment, lines, rays, and angles.

As a reminder:

• Point - a single location in space.
• Will look like a dot with nothing attached. 

• Lines segment - a straight row of points that starts at one point and ends at another point.
• BOTH ends will have point. (see picture below.)

 

• Line - a straight row of points that goes on forever in both directions
• Continues in both directions for ever and ever and ever!
• Each end will have an arrow. 

• Rays - a straight row of points that starts at one point and goes on forever in one direction.
• Think of the sun! The light from the sun shoots from the sun straight to Earth.
• ONE end will have an arrow and ONE end will have a point.

• Angles - two rays, lines, or line segments that meet at a common point. 
• Makes V shapes.
• Will look like two rays.
• Types we will cover:
• Acute (1-89 degrees)
• Right (90 degrees)
• Obtuse (91-179 degrees)
