[size=150]Follow these steps for congruent segment constructions:[/size][br]1) Using the LINE TOOL, make a segment CD of any length, but longer than AB.[br] [i][color=#0000ff]Select the LINE TOOL, the click anywhere to mark C, then click anywhere to mark D[/color][/i][br]2) Using the COMPASS TOOL, create a circle with radius AB and center point C. [br][i][color=#0000ff] Select the COMPASS TOOL, then click on A, then click on B, then click on C[/color][/i][br]3) Using the POINT TOOL, mark the intersection of circle C and segment CD as E.[br] [i][color=#0000ff]Select the POINT TOOL, then carefully click where the two intersect, F should appear as a black point, not [br] purple[/color][/i]

Construct a segment that is exactly TWICE the length as segment AB.
