To find the diagonals we need to use Pythagorean's Theorem, where the diagonals are hypothenuses. Also, , beacuse rectangles have congruent diagonals, which intercect equally. That means,. Now, angles 11 and 4 are alternate interior angles which are congruent, because a rectangle has opposite congruent and parallel sides.

Let's go over a few key words so we're all on the same page. Remember that a polygon is a two-dimensional shape with sides drawn by straight lines no curves which together form a closed area. Each point on a polygon where two sides meet is called a vertex. At each vertex, there is an interior angle of the polygon. A square, for example, has four interior angles, each of 90 degrees. If the square represented your classroom, the interior angles are the four corners of the room. For example, a triangle has 3 angles which add up to degrees.
