Circle Terminology


Big Wheel
Originally uploaded by natalieb.
Before we start using Geometer's Sketchpad to investigate properties of circles we need to define some parts of the circle. Using the Math Dictionary link in our blog define the following terms:

Circle
Radius
Diameter
Chord

Mark sure to write these definitions in your notebook. You may even want to draw a diagram to help illustrate these parts of a circle.


This picture of a bicycle wheel illustrates some of the parts of a circle.

Challenge: The long weekend is before us. Anyone who brings in or e-mails me a picture of a real world example of circles receives a bonus mark on their next exam. Make sure that you can explain to me where this picture was taken, ie. the city or town, the building location etc... Wouldn't it be cool to post these to our blog!!!!!
