^, on whose hypotenuse,nm, lies the point a in space; andon whose base, vJm^, lies a*. A triangle of this kind, (ui^,is shown in Fig. 99. Let this triangle be rotated on nn*as an axis, into V, giving w«*7rt* as its true shape. Thepoint a will be found on this line, at a distance from m^ equalto… … Fio. 106 VI, § 951 POINTS, LINES, AND PLANES 105 This point (a) being established, we know the height of thepoint o in space; hence o will lie on a horizontal througha. The distance from m* to o*, which will lie on mV, aspointed out above, will be equal to m^a* It is now easy tolocate a* by…
