Answer 1

Question:-

In a parellelogram ABCD,<D = 112 degrees find <A and <B.

Given:-

<D = 112 degrees,

Answer:-

In a parallelogram,

Opposite angles are congruent.

&

Adjacent angles are supplymentary.

Therefore;

<D = <B

hence, <B = 112°

2nd,

<D & <A are adjacent angles.

<D + <A = 180°

:. 112 + <A = 180°

➡️ <A = 180 - 112

= 78°

Ans:- <A = 78°, and <B = 112°
