In this lesson,we exploredpoints,lines,and planes.Specifically, we havelearned:
- The significanceof the undefinedtermspoint,line, and plane.
- The significanceof definedtermsincludingspace,segment,and ray.
- How to identifyand applybasicpostulatesof points,lines,and planes.
- How to drawand labelthe termsyou havestudiedin a diagram.
Theseskillsare the buildingblocksof geometry. It is importantto havetheseconceptssolidifiedin your
mindas you exploreothertopicsof geometryand mathematics.
Pointsto Consider
You can think of postulatesas the basicrulesof geometry. Otheractivitiesalso havebasicrules.For example,
in the gameof soccerone of the basicrulesis that playersare not allowedto use their handsto movethe
ball. How do the rulesshapethe way that the gameis played?As you becomemorefamiliarwith the geo-
metricpostulates,thinkabouthow the basic“rulesof the game”in geometrydeterminewhatyou can and
cannotdo.
Now that you knowsomeof the basics,we are goingto look at how measurementis usedin geometry.
