The radius AL is equal to the radius AD : but AD is equal to FM ; therefore AL is
equal to FM . ... as the squares of their radii ; therefore , since the square of the
radius FM is equal to the squares of the radii FL and FG , the circular section of
the ...

If the triangle be right - angled , any unknown part may be found by the following
proportion : - As radius Is to either leg of the triangle , So is tangent of its adjacent
angle To the other leg ; And so is secant of the same angle To the hypothenuse ...

Then EC will be the smaller radius , and EC added to AD will be the longer radius
. For arches whose height is greater than their half width ( fig . 6296 . ) , draw CF
and BE perpendicular to AC , then EC will be the smaller radius ; and ÉC added ...
