Do you know what an equilateral triangle is? Do you know what a midpoint of a line <BR>segment is? And the properties of the 30°-60°-90° <BR>triangle? Then see if you can do this challenge. Draw two points A and B on the x-axis and see if you could find the formula for the <BR>coordinates of the point C so that triangle <BR>ABC is an equilateral triangle. The coordinates must be dynamic. That is, I <BR>must be able to move A and B and always get an equilateral triangle. Good luck!
