When I draw a diagram, calling the trapezoid ABCD with A and D at the bottom, I see that the length from where the altitude from B and C hits AC to D is 8 from the pythagorean theorem. But the 6 looks a lot bigger. Also, how to find the smaller base?!

**Henry**, Tuesday, February 19, 2013 at 8:18pmAB = CD = 10.

A = D = 45o.

h = 10*sin45 = 7.07 = Altitude

CF = h/sin45 = 7.07/sin45 =10= Diagonal

BC = EF = CF*cos45 = 10*cos45 = 7.07 =

Short base.

AB = CD = 10.

h = Diameter = 2*3 = 6=Ht. or altitude.

Draw altitudes CE and BF

Draw diagonal CF which bisects BCE and

BFE. Therefore, CFE = 45o

tan45 = h/BC = 6/BC

BC = 6/tan45 = 6. = Shortest base.
