angle simbi, inowanzozivikanwa sesimbi yemakona, isimbi refu ine mativi maviri akaenzana kune rimwe nerimwe. Kune simbi yakaenzana yemakona uye simbi isina kuenzana yemakona.Kufara kwemativi maviri esimbi yakaenzana kunoenzana. Iyo yakatarwa inoratidzwa mu mm yehupamhi hweparutivi × upamhi hweparutivi × mativi ukobvu. Zvakadai se“∟ 30 × 30 × 3″, kureva, simbi yemakona yakaenzana nehupamhi hweparutivi hwe30mm uye ukobvu hweparutivi hwe3mm. Inogonawo kuratidzwa nemuenzaniso. Iyo modhi ndiyo centimita yehupamhi hwedivi, senge ∟ 3 × 3. Iyo modhi haimiriri zviyero zveakasiyana mativi makobvu mune imwecheteyo modhi, saka kumucheto kwehupamhi uye kumucheto ukobvu zviyero zvemakona simbi zvichazadzwa zvizere mukati. chibvumirano uye mamwe magwaro ekudzivirira kushandisa modhi chete. Tsanangudzo yekupisa yakakungurutswa yakaenzana gumbo kona simbi ndeye 2 × 3-20 × 3.
