A regular polygon has equal sides in length and angles.
a regular polygon
A parallelogram is a four sided polygon with opposing parallel sides of equal length. Then if it has four right angles, the polygon becomes a rectangle.
a polygon with all sides the same length and all angles the same measure is called?
A rhombus. More information... The no right angles is throwing me, but I will add this comment: A square A four-sided polygon having equal-length sides meeting at right angles. The sum of the angles of a square is 360 degrees. A Parellelogram is a four-sided polygon with two pairs of parallel sides. The sum of the angles of a parallelogram is 360 degrees. A Rhombus is a four-sided polygon having all four sides of equal length. The sum of the angles of a rhombus is 360 degrees. So, a Square is actually a Parellelogram and Rhombus as well; and it has 4 right angles. So... I am not sure that Parellelogram and Rhombus are what you were looking for,
a polygon with 4 right angles and 4 sides of the same length

A rhombus is a quadrilateral polygon with four sides of all equal length.
The right answer is a rectangle.
A square has 4 right angles and 4 equal sides.
You are a rhombus.

Sides cannot be right angles whatever the figure because sides are sides and not angles, the answer you are looking for is a rhombus.
