A four-sided shape with one right angle is a quadrilateral. There is no more specific term, unless it has more than one right angle or has equal sides.
The equation for the size of an interior angle of an n-sided regular polygon is (n-2)180/n. When n=7, the interior angle of a regular sided shape would be 5x180/7 or approximately 128.57. The polygon in the question has an interior right angle (90 degree angle) and thus cannot be a regular shape. A 7 sided shape is called a heptagon. Thus, the shape described in the question is an irregular heptagon.

A right angled pentagon.
An irregular pentagon.
A triangle is a 3 sided shape. There are a few types, Isosceles, Scalene (Acute and Obtuse), Equilateral and the Right angle triangle.

A Square and Rectangle are both a Quadrilaterals(A four sided shape)and have both have 4 Right Angles.In addition,a irregular Quadrilateral(A four sided shape of no sides of the same length)may have a right angle( A 90 degrees angle)but it depends on how you draw it on paper.Cretth 2010
