The length value appears, and commands appear for storing the value in a list. If a value does not appear, you might have selected a peg that is not one of the object’s vector points. Make sure you are measuring a line segment that was defined as part of the object. Note 6. Press   to stop measuring. ATE Geoboard 5. Select the TI 73 list in which you want to store the value, or select QUIT to discard the value. The main Geoboard commands reappear.

Example: Examining the Areas of Squares This example uses Geoboard to demonstrate visually how a square’s area is related to the length of the square’s sides. Quit the Geoboard application, and then clear list L1. You will be using L1 to store measured areas. Restart Geoboard, and select the 8×8 square board. If labels are on, select FMAT (press the  key), and then select LblsOff. 4. Using the DRAW command, draw a 1×1 square in the lowerleft corner. Use the MEAS command to measure the square’s area, and store the value in L1. Starting again in the lower-left corner, draw a 2×2 square, and count the number of small (1×1) squares in the 2×2 square.
