its a hexagon, a regular hexagon has 6 angles that are all the same, when added all together they equal 720 degrees :D
Consider the trapezium (or trapezoid) ABCD such that AD is parallel to BC.Then angles DAB and ABC are consecutive interior angles (or co-interior angles) and sum to 180 deg.Similarly, angles ADC and DCB sum to 180 deg.Therefore, the sum of all four is 180 + 180 = 360 deg.
180 degrees
If you add the values of all four angles in a parallelogram together, the total will be 360 degrees.
