Question

two adjacent angles of a parellogram are congrent what is the measure of each​

Answer 1

Answer:

90°

Step-by-step explanation:

if two angles are congruent then their measures will be equal,

let the two angles be x and y

we know x = y

in a parallelogram sum of adjacent angles is 180°.

therefore,

x + y = 180°

but x = y,

x + x = 180°

2x = 180°

x = 180

2

x = 90°

and x = y so,

y = 90°

Therefore,

Therefore,two adjacent angles of a parallelogram which are congruent will be 90°each
