Then PD=24-t
CQ=3t
Parallelogram:
PD=CQ
So 24-t=3t
t=6
Isosceles trapezoid:
Because BC-AD=2
So if you want to be an isosceles triangle,
The bottom is 4 longer than the top.
That is PD+4=CQ.
So 24-t+4=3t.
t=7
15. Take the midpoint g of AB, and connect EG: quadrilateral ABCD as a square ∴∠ B = 90 ∴∠ BAE +∞ BEA = 90 because AE?ef∴∠bea+∞. Because CF is the bisector of the outer corner of ∠DCB, DFC = 45, ECF = 90+45 = 135, AE=EF agrees with 0| comment.
