11. Adjacent vertex angles are supplementary and opposite angles are equal. If the angles are vertex angles numbered in order around the figure,
.. ∠2 = 12°
.. ∠3 = 168°
13. If the quadrilateral is a parallelogram so that point E is the midpoint of both diagonals, it will be a rectangle when the diagonals are equal length.
.. ae = be
.. x +22 = 3x -18
.. 40 = 2x
.. x = 20 . . . . . will make segments AE and BE the same length
