'EQUILATERAL-ness' of Triangles
This applet is an exploration of the 'EQUILATERAL-ness' of triangles.
If you drag the vertices of the triangle, some measures of properties of
the triangle are shown in the table on the left.
Can you construct a measure of 'EQUILATERAL-ness' based on these measures?
What other measures can you think of? When would those measures be better?
What other questions could/would you ask your students based on this applet?
