Cross Section? (1)

[color=#000000]In the applet below, [/color][color=#0000ff][b]part of a plane[/b][/color][color=#000000] is shown intersecting a [/color][b]cube.[/b][color=#000000] [br][br]The [/color][color=#ff7700][b]orange segments[/b][/color][color=#000000] are [/color][b][color=#ff7700]congruent[/color][/b][color=#000000]. [br][/color][color=#000000]The [/color][b][color=#6aa84f]green[/color][/b][color=#6aa84f][b] segments[/b][/color][color=#000000] are also [/color][color=#6aa84f][b]congruent[/b][/color][color=#000000]. [br][br]What does this [/color][color=#0000ff][b]cross section[/b][/color][color=#000000] look like? [br][br]How could you formally prove your assertion to be true? [/color]
