True Shape
Te topic aio e rekereke ma kakaean ana true shape te surface teuana. Ae nanona ba ko na nako n tei i matan te surface anne ba e na 90 degrees, ke e na "perpendicular" am taratara nakon te surface anne. Noora te aine are e taraa te surface ae barara - e riai n perpendicular am taratara ao e na reke te true shape.
Ok, ngkanne kam na mataku n taian vidclips akanne inano ao ongoraraoi kabarabaraan karekean ana true shape te square pyramid ae koreaki. Ko anganaki te front view ma te top view. Ko na noora te surface are e koreaki n te uraura (red) ao e aki booraoi ma are e barara (slope). Ngkana ko taku ba e a reke i roum ao kataia n katootoonga n am beeba teuana.
2. Kataia ngkanne n te hexagonal pyramid. Korea am Plan ke am Top view, ao am Front. Koreia tao nuukan te axis n te Front view. E na aki wene am korokoro ma e na barara. Kanga n aron am tamnei ae i nano:
2.1. E tia am tamnei n aron aei ao ngkanne katika am points man te cutting plane, ke te section plane. Uringngs am projection lines a riai ni perpendicular nakon te cut surface ke am cutting plane.
