Igitebe Kidafite Umugongo, Ameza Mato Rt ni igitebe kidafite umugongo gishobora no gukoreshwa nk'ameza mato. Igishushanyo cyahumekewe n'umuco w'Ubushinwa wa tangram, kandi kigizwe n'ibice bitatu bifite inguni z'imbibi (right-angle). Ibyuma bibiri bya alumini bifite imiterere ya "L" kandi bingana, ni byo bishyigikira igice kimwe cy'ikibaho cy'ubwoko bw'igiti cya ash gifite inguni y'imbibi. Ibyuma bya alumini bifite ubugari bwa milimetero 6, kandi bikorwa hakoreshejwe uburyo bwa laser cutting na machine bending. Ibi bice bitatu byose bihuzwa hakoreshejwe amasukuru, bityo abakoresha bashobora kubyubaka no kubisenya ubwabo. Rt ifite ingano ya milimetero 300 ku 300 ku 500, kandi igaragara ku buryo butandukanye bitewe n'aho uyireba.
