Question

Two adjacent angles of a parallelogram are equal. What is the measure of each angle?

Answer 1

Let's find the value of each angle of the given parallelogram.

The adjacent angles of a parallelogram are equal.
The sum of adjacent angles of parallelogram $180°$
Assume the adjacent angles to be $x$ and $x$.
Therefore, $x+x=180°$
$\Rightarrow$ $2x=180°$
$\Rightarrow x=90°$
Therefore, the measure of each of the adjacent angles is $90°.$
