#1 - PQ is 12- sq.rt of 85...roughly 2.78

I'm a little confused. PQ is 12 minus the sq.rt of 85?

root 85 is 9.219544457 12-rt 85 equals 2.78

But there's no way in hell that PQ can be 2.78. Since PQ,PD, and PA are congruent, the PA and PD would also be 2.78. That won't work, because in any given triangle, any 2 sides must add up to a number greater than the third side, but 2.78x2= 5.56

5.56 is not > 12
