(1) The insertion may ascend on the lateral face of the radius or may be extended distally to the navicular, trapezium , or base of the third metacarpal bone.(2) The distal row of carpals includes the hamate, capitate, trapezium , and trapezoid, which are closely approximated to the metacarpals.(3) What is the length of the top edge, x, in this new trapezium ?(4) These involved, in addition to the base of the first carpometacarpal joint, the trapezium , navicular, surrounding fascial structures or the abductor pollicis brevis muscle.(5) With the help of square, rhombus, rectangle, parallelogram, trapezium , equilateral, isosceles, diamond and kite shapes the direct and indirect approaches to teach the Pythagoras Theorem and other mathematical concepts is possible.(6) In particular he finds, in book 1, the centre of gravity of a parallelogram, a triangle, and a trapezium .(7) They have been made in many shapes: triangular or trapeziform, ├ö├ç├┐pig's head├ö├ç├û shape (a trapezium with concave ├ö├ç├┐cheeks├ö├ç├û, popularly known in Italy as strumento di porco), wing or harp-shaped, or rectangular.(8) Occasionally, a slip also passes to the fourth metacarpal or to the trapezium .(9) The movements of the thumb are dictated by the saddle-shaped articular surface of the base of the first metacarpal, which articulates with the trapezium .(10) On plan the auditorium is a trapezium rising three levels high inside its rectangular confines with rehearsal and dressing rooms fitted around two edges.(11) Also, the gold point makes the three equal-length sides SP = PQ = QR in the resulting trapezium so it is trisosceles (to use Scott's phrase) and so is a special isosceles triangle.(12) The types of shapes for which the area is calculated include triangles, rectangles, circles, trapeziums .
