What is a 5 sided polygon with two right angles?

A five-sided polygon with two right angles is called a pentagon. The specific arrangement of the right angles can vary, but a common example is an irregular pentagon where two adjacent angles measure 90 degrees. The other three angles must sum to 270 degrees to satisfy the interior angle sum of 540 degrees for a pentagon. This results in a variety of shapes depending on the lengths of the sides and the measures of the remaining angles.
