A right triangle is a triangle with one angle measuring 90 degrees. A rectangle is a four-sided polygon (quadrilateral) with opposite sides equal and all angles measuring 90 degrees. A square is a special type of rectangle where all four sides are of equal length. Together, these shapes are fundamental in geometry, often studied in relation to each other due to their properties involving right angles.

A rectangle is a quadrilateral with 4 right angles (90 degrees) and two sets of parallel lines. The definition of a rectangle includes the the shape of a square, but a square has an added rule, that all sides must be equal. So a square is a rectangle. Oblong is a term for non-square rectangles.
A square is also a rectangle, a rhombus, a parallelogram, and a quadrilateral.
