WebTriangle ABE is isosceles, its base angles have sum 180 -108 = 72 Each base angle is half that, so angle ABE has measure 36 . Angle AED is an interior angle of the regular pentagon, so it has measure 108 . Angle AEB is the other base angle of the isosceles triangle ABE, so it is 36 . Angle BED = Angle AED - Angle AEB = 108 -36 = 72 Edwin
