Quadrilateral ABCD is a parallelogram wherein two consecutive angles are supplementary, what is the ratio of angle A to angle D if tge measure of angle A is 40°
Since angles A and D are opposite angles in the parallelogram, they must be equal in measure. Therefore, if angle A is 40°, then angle D is also 40°.
The ratio of angle A to angle D is therefore:
Angle A / Angle D = 40 / 40 = 1
Therefore, the ratio of angle A to angle D is 1.
