## DIRECTIONS:

In the GeoGebra applet below,
1) Select the CIRCLE WITH CENTER THROUGH POINT tool.
Use this tool to plot a circle with center

*A*that passes through*B*. 2) Keep this same tool selected. Now this time, construct a circle with center*B*that passes through*A*. 3) Use the INTERSECT tool to plot the point(s) at which these 2 circles intersect. One of these points should be labeled*C*. 4) Use the POLYGON tool to construct the triangle with vertices*A*,*B*, and*C*. 5) Now select the MOVE tool. Move point(s)*A*and/or*B*around.## 6)

How would you classify triangle *ABC* by its sides? Why is this?

When you're done (or if you're unsure of something), feel free to check by watching the quick silent screencast below the applet.
