Question

ABCD and DEFG are both parallelograms. If angle D= 40° , find angle E, angle F, angle B, angle C and angle A.

Answer 1

Step-by-step explanation:

angle D = angle B ( opp angles of a parallelogram are equal. )

angle B = 40

angle D = angle F

angle F = 40

angle D + angle A = 180. ( adjacent angles are supplementary. )

40 + angle A = 180

angle A = 180 - 40

= 140

angle A = angle C

angle C = 140

angle D + angle E = 180

40. + angle E = 180

angle E = 180 - 40

= 140
