1.)Drag the parallelogram down, and it builds 180º with the angle of the isosceles triangle.

2.) Isosceles triangle => 64º

3.)180-64 => 116º

4.)Opposing angles in a parallelogram are identical.

--------------------------

Yellow Triangle = 180 - 52 - 64 = 64 degrees

Based on opposite angles of a parallelagram, Green Triangle angle (?) = 180 - 64 = 116 degrees.
