rhombus vs. parallelogram
rhombus vs. parallelogram: What's the difference?
A parallelogram is a shape with four sides in which the opposite sides are parallel to each other. A rhombus is a specific type of parallelogram in which all four sides are the same length. When the four corners of a parallelogram are right angles (meaning none of the sides are slanted), it’s called a rectangle. When the four corners of a four-sided shape are right angles and its sides are all the same length, it’s called a square.
