 <\/p>\r\n

Trapets<\/strong><\/span> on kumer nelinurk, mille kaks k\u00fclge on omavahel paralleelsed ja kaks k\u00fclge mitte. Trapets<\/strong> tuleneb kreeka s\u00f5nast trapezion (lauake).
\r\nTrapetsi paralleelseid k\u00fclgi nimetatakse trapetsi alusteks (AB ja DC v\u00f5i a ja b)<\/strong> ja \u00fclej\u00e4\u00e4nud kaht k\u00fclge haaradeks (AD ja BC v\u00f5i c ja d)<\/strong>.
\r\nTrapetsit, mille haarad on v\u00f5rdsed, nimetatakse v\u00f5rdhaarseks trapetsiks. <\/strong><\/span><\/p>\r\n

Aluste vahelist kaugust nimetatakse trapetsi k\u00f5rguseks (DE =h).<\/strong>

Trapetsi keskl\u00f5iguks<\/strong> (FG) nimetatakse trapetsi  haarade keskpunkte \u00fchendavat l\u00f5iku  (AF=FD ja BG=GC).<\/p>\r\n
