Question

2 adj. Angle of 11gm have equal measure find the measure of each angle

Answer 1

Step-by-step explanation:

let the two adjacent angles be X

as opposite angles are equal therefore all angles will be equal to X

$x + x + x + x = 360$

as the angles of a quadrilateral is equal to 360 degreed and a parallelogram is a quadrilateral

hence

$4x = 360 \\ x = 360 \div 4 \\ x = 90$

hence the angles are 90 degrees each

therefore the parallelogram is a rectangle and each angle is 90 degrees each
