One of the angles of the parallelogram is 55 degrees. find the rest of the corners

In order to find the angles of a parallelogram, we will recall the properties of the angles of a parallelogram.

But first, consider the condition of the problem. It says that one of the angles of the parallelogram is 55 °.

So, the opposite angles of the parallelogram are equal to each other, we conclude that we already know one pair of angles and it is equal to 55 °.

It is also known that the sum of the angles adjacent to one side is 180 °.

Let’s calculate the degree measure of one more angle: 180 – 55 = 125 °.

The opposite angle is 125 °.

Answer: 55 °; 125 °; 125 °.
