[size=150]1) Use the POLYGON [icon]/images/ggb/toolbar/mode_polygon.png[/icon] tool to construct hexagon [i]ABCDEF[/i]. [br]2) Select the ANGLE [icon]/images/ggb/toolbar/mode_angle.png[/icon] tool. Then click anywhere inside the polygon. [br]3) Go to the Algebra view (click calculator icon upper left). [br][br]4) Calculate the[b] sum of the measures of the interior angles of this hexagon[/b], making [br] sure to add the Greek letters (and not single numerical values)! If you forget how to do this, [br] [url=https://youtu.be/v2tYFqcShSg]click here to see it again in the context of a triangle[/url]. [/size]
[size=150]Select the MOVE [icon]/images/ggb/toolbar/mode_move.png[/icon] tool in the app above. Move any one (or more) of the triangle's vertices around. What can we conclude about the [b]sum of the measures of the interior angles[/b] of any hexagon? [/size]
