[b]Step 1.  On paper, make a Report Table:[/b][br][table][tr][td][u]Angle[/u][/td][td][u]Estimated Degrees[/u][/td][td][u]Measured Degrees[/u][/td][/tr][tr][td]1[/td][td][/td][td][/td][/tr][tr][td]2[/td][td][/td][td][/td][/tr][tr][td]3[/td][td][/td][td][/td][/tr][tr][td]4[/td][td][/td][td][/td][/tr][tr][td]5[/td][td][/td][td][/td][/tr][/table][br][b]Step 2. Estimate [/b][br]Turn off the protractor display.Use the MOVE tool [icon]/images/ggb/toolbar/mode_move.png[/icon]to move Point D and change the size of the yellow angle.[br][br]Now, with the protractor still turned off, estimate the size of the angle you created and enter your estimate in the middle column in the Report Table.[br][br][b]Step 3. Check Your Measurements[/b][br]Now turn on the protractor display.  [br]Use the protractor to actually measure the angle you created. [br]Enter this value in the Report Table next to your estimate.[br][br]Construct four more random angles and repeat Steps 1 and 2 for all of them, completing the Report Table.
