Activity #1__Move Tool

Directions

Under BASIC Tools, click the Move tool to: 1. move the line segment AB. 2. change the length of the line (click onto point B and adjust). 3. move the triangle. 4. change the shape, angle, and length of the triangle.

QUESTION

Line segment AB has a value (length) of 4.04. The length of any line in GeoGebra is not automatically shown. In other words, you have to use a "tool" to activate it. Explain how I got this value to show up?. (hint: click the move tool, then click onto the line).
