Now You Know

After completing this tutorial, you will be able to complete the following:

  • Identify intersecting lines.
  • Identify lines that intersect a plane.
  • Identify collinear points.
  • Identify intersecting planes.

Everything You'll Have Covered

In the Activity Object, statements are true only when they can be proven true. Students will need to read each statement and analyze the figure provided to determine if the statements are true or false. You may wish to provide a model using a Think Aloud to demonstrate how to determine whether a statement is true or false. A detailed Think Aloud is provided in the One-Computer Class Strategy section of this document.

A plane can be described as a "flat" surface extending infinitely in all directions.

In this Activity Object, most of the written statements are replaced by expressions using the following symbols.

Symbols are often used to provide a quick way to demonstrate the relationships between specific points, lines, and planes. Students will be exposed to symbols like the ones used in this Activity Object as they advance in their Geometric studies. This Activity Object is challenging because students be comfortable with reading and analyzing expressions using the symbols. Be sure to clearly introduce each symbol prior to exploring this Activity Object. You may also choose to post chart paper with the symbols and definitions on the wall in the classroom as a visual tool for all students. The table of on the next page explains the various symbols used in this Activity Object.
