[b][color=#0000ff]1) Open Geogebra 3D Graphics window .[br]2)Take a cube from input bar or using tool from 3D graphics,[br]3)Take a pmd1 =Pyramid(A,B,C,D,F) from Input bar then colour it[br]4)Take a line AB by using line tool ,[br]5) Take input bar then text Rotate(pmd1,α ,AB)Then click on create slider Rotate line AB for slider (0-90°) [br]6)Take a pmd2 =Pyramid(D,E,G,H,F) then colour it, [br]7) Take input bar the text Rotate(pmd2,α ,GH) .[br]8) Similarly Take another one Pyramid 3 then colour it ,[br]9) Then show or hide object or level line ,Axes ,Greed and Plane for good visualization.[br]10) Finally rotate it then watch the visualization of cube and pyramid.
