Question

2. Two adjacent angles of a parallelogram are in the ratio 1 : 1. Find the measures of all the angles.​

Answer 1

Answer:

let ABCD is a parallelogram.

and angles be DAB, ABC, BCD, CDA

and given angles be x and x .

we know that

adjacent angles are supplementry

so,

x+ x = 180°

2x= 180°

x= 90 °

so two angles be of 90° and 90° .

similarly other two angles are adjacent to given two angles .

so, all angles be of 90° .
