Understanding Rhombus

The video tutorial explains what a rhombus is, describing it as a quadrilateral with equal sides and parallel opposite sides. It details the properties of a rhombus, including congruent opposite sides, perpendicular diagonals, and the formation of congruent interior triangles. The video also covers formulas for calculating the perimeter and area of a rhombus, and compares rhombuses to parallelograms and squares. It concludes with a reminder that all squares are rhombuses, but not all rhombuses are squares.
