This applet is an exploration of the 'EQUILATERAL-ness' of triangles.[br][br]If you drag the vertices of the triangle, some measures of properties of [br]the triangle are shown in the table on the left.[br][br]Can you construct a measure of 'EQUILATERAL-ness' based on these measures?[br][br]What other measures can you think of? When would those measures be better?[br][br][color=#ff0000][i][b]What other questions could/would you ask your students based on this applet?[/b][/i][/color]
