Points, lines, and planes

The  exercise appears under the Geometry Math Mission(HIDDEN). This exercise introduces and practices notation and vocabulary for the basic geometric objects.

Types of Problems
There are three types of problems in this exercise:


 * 1) Answer the yes or no question: This problem asks a yes or no question about a given 3D diagram. The student is asked to select the correct answer.Plp1.png
 * 2) Give an alternate name: This problem has a 3D diagram and gives the name for an object from the diagram. The student is asked to select an appropriate alternate name from a multiple choice list.Plp2.png
 * 3) Provide a correct name: This problem has a 3D diagram and a prompt to name one of the objects from the diagram. The student is expected to write a correct possible name in the space provided.Plp3.png

Strategies
Knowledge of the basic definitions and notations for points, lines, and planes are encouraged to ensure success on this exercise.
 * 1) A point is the basic 0D shape, a line is 1D, and the plane is 2D. Into the third dimension, the basic shape is called a space.
 * 2) Points are named by single letters, lines only require two point, and planes only require three points.
 * 3) Colinear means "can be drawn on the same line" even if no line exists in the actual diagram.

Real-life Applications

 * 1) The names of these objects show up in future math courses are treated as basic definitions.
 * 2) The fact that three points determine a plane is the reason objects like tripods and bar stools can stand up straight on slanted surfaces.
