Ukucaca kokubona6 cpd · 20/100 (est.)

Ibanga lokubona180°

Umuntu ≈ 60 cpd (20/10)

Ukubona kuka-i-seal kucace kangakanani?

Amehlo ayo ahlukanisa cishe ama-cycles angu-6 ngedigri (20/100 (est.)), kanti umuntu ufinyelela cishe ku-60 cpd (20/10). Ibanga layo lokubona lisabalala cishe ngo-180°.

i-seal ubona kanjani umuntu?

Amehlo ayo ahlukanisa cishe imijikelezo engu-6 ngedigri, kanti awakho angu-60, ngakho ubuso kumele busondele cishe izikhathi ezingu-10 ukuze ibone imininingwane oyibonayo. Isimo sakho nokunyakaza kwakho kufika kucacile; ukubukeka kobuso bakho akufiki.
