More Circles...

Today we learned 2 new circle theorems. Below are screenshots of the "doodles" and the euklid models along with the "then and now" question. We also had an enthusiastic debate over cell phone etticite.

Circle Geometry

First we started off with opening EUKLID DynaGeo. It is a good tool to use for circle geometry. Mr. Max started the lesson on Circle Geometry by asking us the most basic question... What is a Circle? a circle is a set of points in a 2D plane, such that all points are EQUIDISTANT from a centre point. We have to use the "Internet" to find the definitions to these circle words.

-Radius
-Diameter
-Circumference
-Chord
-Secant
-Tangent
-Minor/Major Arc
-Arc
-Segmant
-Sector
-Intercepted Arc
-Intercepted Angle
-Angle
-Central Angle
-Inscribed Angle
-Quadrilateral
-Cyclic Quadrilateral

...and we have to find what they are on a Diagram that Mr. Max created.
