Square from Diagonal

If you have a few moments – do the construction, upload it and take the survey.
 * Question:** I would like to know how you might use/change this problem for your classroom.
 * Would this be how you might do this exploration? Would you fix the endpoints? Would you turn off the Algebra View? Can the kiddies do this? Are the questions good? I put these questions in this Google Survey: **** [] **

What makes it look like the other diagonal? What tools in GeoGebra to we need to draw the “real” diagonal? Of course, they need to find the properties, but they also need to “order” and choose their tools. 3. **Use GeoGebra to draw a real diagonal.** (Here is little Jing solution: []) Questions: **Is this the only square for this diagonal? If yes, does this mean I know everything about a square from its diagonal? What does it mean to know everything about a square?** media type="custom" key="6615421"
 * Double click below on the GeoGebra worksheet to open it on your computer. **
 * The line segment AB is the diagonal of a square. **
 * Our goal: Draw the other diagonal and then draw the square. **
 * Our steps:**
 * 1. ****Draw a line segment that “looks” like the other diagonal.**
 * 2. ****Delete your fake diagonal.**

Responses: ** [] ** It is 4AM so bad voice J so I wrote down my steps: a. Find the midpoint C of the diagonal (diagonals of quadrilaterals intersect at their midpoint) using // midpoint tool //. b. Draw a perpendicular to the diagonal at C using // perpendicular tool //. c. Draw a circle with center C and point A using // circle with center and point tool // d. Find the endpoints of the other diagonal with // intersection tool //. Draw square with // polygon tool //.
