Find the length of the shorter base of the trapezoid.

**Henry**, Tuesday, November 30, 2010 at 2:29pmThe non-parallel sides of an isosceles

trapezoid are equal and form congruent rt triangles when the altitude is drawn. The base of the rt tiangles can be calculated:

X^2 + Y^2 = Z^2,

X^2 + 4^2 = 5^2,

X^2 + 16 = 25,

X^2 = 25 - 16,

X^2 = 9,

X = 3.

2X + B2 = B1,

2*3 + B2 = 11,

6 + B2 = 11,

B2 = 11 - 6,

B2 = 5.
