Understanding the Area of a Rhombus

The video tutorial explains how to prove that the area of a rhombus is equal to half the product of its diagonals. It begins by discussing the properties of rhombi and parallelograms, such as congruent sides and bisecting diagonals. The tutorial then demonstrates how to use triangle congruency to calculate the area of a rhombus by dividing it into two congruent triangles. The area of one triangle is calculated using the base and height, which are the diagonals of the rhombus. Finally, the video concludes by deriving the area formula and suggesting further exploration of parallelogram areas.
