    Position the bases horizontally. The slope of the left side will be the height of the triangle divided by half of the base of the triangle. To double the slope without changing the height, reduce the length of the half-base (by a factor of 2).

    The slope is the height divided by half the length of the base. The height is the same. The slope is halved going from A to B. Therefore the base is doubled.

    s1=2h/b s2=2h/(2b)

    s2 = 1/2 s1
